What is IPA? Full form, other names, CAS, HSN and UN number
IPA stands for isopropyl alcohol, also called isopropanol or 2-propanol: formula C3H8O, CAS 67-63-0, HSN 2905 12 20, UN 1219 (Class 3, Packing Group II). Supreme Petro Chemicals is a Chennai importer and bulk distributor, not a manufacturer, and supplies two grades: Technical (99.80% w/w min, GC) and IP (99.0% v/v min), with a batch Certificate of Analysis supplied with every delivery.
On a grade label, IP means Indian Pharmacopoeia, which is a separate thing from IPA. N-Propanol (CAS 71-23-8) is a different alcohol and a separate product with its own tariff line.

IPA grades: Technical 99.8% versus IP (Indian Pharmacopoeia) 99.0%
SPC lists two IPA grades. Technical grade is specified at 99.80% w/w minimum by GC; IP grade at 99.0% v/v minimum. The units differ (weight versus volume), so the two assay figures cannot be compared directly. Technical grade is not a pharmacopoeial, food or pharma grade.
BP (British Pharmacopoeia) limits are near-identical to IP and can be discussed on request; ask before assuming BP supply. SPC lists only the two grades above for IPA on this page.
| Point of comparison | Technical grade | IP grade |

IPA specification: typical limits for Technical and IP grade
Technical grade IPA is specified at 99.80% w/w minimum assay (GC), water 0.10% w/w maximum, non-volatile residue 0.005% w/v maximum, benzene 2 mg/kg maximum and colour 5 APHA maximum. IP grade is 99.0% v/v minimum with peroxides nil. Limits below are the TDS ranges, not single-point values.
Some Technical-grade limits are quoted by one maker only on the TDS, and the table marks which. Where the two makers publish different test conditions (for example density at 25 C or at 20 C, or acidity in ml of 0.1 N NaOH versus mg/kg), both are shown with the maker basis. Confirm the figures for your delivery against the batch Certificate of Analysis.

What is IPA used for? Chemicals for ink, electronics, pharma and sanitiser makers
IPA is a fast-evaporating, water-miscible alcohol. SPC supplies it as a chemical for printing ink and coating manufacturers, electronics and precision-cleaning users, disinfectant and sanitiser makers, pharmaceutical processors, cosmetics and perfumery manufacturers, and laboratories that need an extraction solvent. The explanations of why a solvent property suits a use are general knowledge, not SPC specifications.
- Printing inks and coatings (flexo and roto printing): used as a solvent or co-solvent. Quick evaporation helps inks dry fast, and miscibility with water and other solvents makes it easy to blend.
- Electronics and precision cleaning: used to wipe and degrease parts. Little residue is left when the grade is low in water and non-volatile matter, which is why those limits matter to these buyers.
- Disinfectants and sanitisers: used as a raw material, normally diluted with water to a working strength before use. See our IPA concentration guide in the guides section of this page.
- Pharmaceutical processing: used as a process and extraction solvent. Ask for IP grade and let your QA team approve the grade; Technical grade is not a pharmacopoeial grade.
- Cosmetics and perfumery: used as a solvent in formulations. Confirm suitability of the grade with your own regulatory team.
- Extraction solvent and R&D laboratories: used for extraction and general laboratory work, within the grades listed on this page.
- Home care and automobile-related formulations: listed on this site as industries that buy IPA.
IPA packing and supply from Chennai: drums, IBC and bulk tanker
SPC lists IPA in 200 L MS barrels, 1000 L IBC tanks and bulk road tankers. Dispatch is arranged from Chennai (warehouse: Redhills; head office: Periyamet). Tell us the grade and pack you need when you enquire; pack formats are confirmed at the time of quotation.
Dispatch cities named on this site for IPA include Coimbatore, Madurai, Hosur, Bangalore and Hyderabad. General knowledge: the TDS density ranges run from 0.783 to 0.787 depending on maker and temperature, so a 200 L barrel holds roughly 156.6 to 157.4 kg and a 1000 L IBC roughly 783 to 787 kg. This is arithmetic for planning only, so always state whether your quantity is in litres or kilograms; the invoice weight and Certificate of Analysis govern.
| Pack format | Where it is listed |
|---|---|
| 200 L MS barrel | SPC product data, packaging |
| 1000 L IBC tank | SPC product data, packaging |
| Bulk road tanker | SPC product data; Technical-grade TDS packaging note |
| Drums (maker-filled) | Technical-grade TDS: drummed IPA also produced by DFPCL |
| IP grade | IP-grade TDS packaging note: as per order |
IPA SDS, TDS and Certificate of Analysis: documents with every order
A batch Certificate of Analysis is supplied with every delivery, and the SDS and both TDS files are available from the documents on this page. The TDS shows typical limits; the batch Certificate of Analysis reports the results for the batch delivered.
- Safety Data Sheet (SDS), Revision 3.1, July 2026
- Technical-grade Technical Data Sheet (TDS), SPC-TDS-ALC-001
- IP-grade Technical Data Sheet (TDS), SPC-TDS-ALC-006

- Scope: the document set covers Technical and IP grade only, and Technical grade is not a pharma or food grade.
Is IPA flammable? Flash point, boiling point, storage and handling
Yes. IPA is a highly flammable liquid and vapour with a flash point of 12 C (closed cup). Boiling point is 82.5 C and auto-ignition 399 C. It causes serious eye irritation. The SDS calls for storage in a well-ventilated place, tightly closed, away from heat, sparks and ignition sources. As general knowledge, a flash point this low means vapour can ignite near ordinary room temperatures without heating.
The vapour is heavier than air (vapour density 2.07, air = 1), so general knowledge says it can collect at low levels and travel along floors to a distant ignition source. The SDS calls for keeping away from heat, sparks, open flames and hot surfaces, non-sparking tools, and explosion-proof electrical equipment.
Keep IPA away from strong oxidising agents (the SDS lists nitric acid, chlorine, permanganates and peroxides) and concentrated acids. Read the SDS before handling; this page summarises it and does not replace it.
| Property | Value |
|---|---|
| Flash point | 12 C, closed cup |
| Boiling point | 82.5 C at 760 mmHg |
| Melting point | -89 C |
| Auto-ignition temperature | 399 C |
| Flammable limits in air | LFL 2.0% v/v, UFL 12.7% v/v |
| Vapour pressure | 33 mmHg at 20 C |
| Vapour density | 2.07 (air = 1) |
| Solubility in water | Miscible |
| Hazard wording (TDS) | Highly flammable liquid and vapour; causes serious eye irritation |
| Transport | UN 1219, Class 3, Packing Group II |
IPA HSN code, UN number and standards for India
The HSN code for isopropyl alcohol is 2905 12 20. For transport it is UN 1219, Class 3 flammable liquid, Packing Group II. N-propanol sits on the neighbouring sub-line ending in 10, so the two alcohols must not be mixed up on an invoice or import filing.
HSN codes follow chemical identity: isopropyl alcohol (CAS 67-63-0) and n-propanol (CAS 71-23-8) are different molecules with different tariff lines, so confirm the line with your customs broker or tax adviser before filing. Duty and GST rates change and are not published on this page.
The Technical-grade TDS cites IS 2631 for one of the two named makers (Deepak Phenolics) and the IP-grade TDS follows Indian Pharmacopoeia limits. SPC does not certify conformity itself; the batch Certificate of Analysis is the record for each delivery.

IPA versus n-propanol, ethanol and methanol
IPA (2-propanol) is a three-carbon secondary alcohol. N-propanol has the same carbon count but is a primary alcohol with a different CAS number and tariff line. Ethanol has two carbons and methanol one. They are not interchangeable in a specification without the buyer's own technical approval.
General knowledge: alcohols differ in evaporation rate, toxicity, regulatory control and compatibility with plastics and resins, so a substitution should be tested and approved by your own technical team. Specification values for ethanol and methanol are not given here because SPC does not publish them on this page.
| Alcohol | CAS number | Carbon atoms | Type |
|---|---|---|---|
| Isopropyl alcohol (IPA, 2-propanol) | 67-63-0 | 3 | Secondary alcohol |
| N-Propanol (1-propanol) | 71-23-8 | 3 | Primary alcohol |
| Ethanol | 64-17-5 | 2 | Primary alcohol |
| Methanol | 67-56-1 | 1 | Primary alcohol |

Frequently Asked Questions
What is the full form of IPA, and what are its other names?
IPA stands for Isopropyl Alcohol, also called isopropanol, 2-propanol or propan-2-ol, with formula C3H8O. It is not the same as IP, which on a grade label means Indian Pharmacopoeia, and it is not n-propanol, which is a different alcohol with its own CAS number and tariff line.
What is the CAS number of isopropyl alcohol?
The CAS number of isopropyl alcohol is 67-63-0, and its EC number is 200-661-7. Check the CAS number on any quotation or Certificate of Analysis, because n-propanol, a different alcohol, carries CAS 71-23-8.
What is the HSN code for isopropyl alcohol in India?
The HSN code for isopropyl alcohol is 2905 12 20. N-propanol sits on the neighbouring line 2905 12 10, so use the CAS number on the document to confirm which alcohol is being filed. Duty and GST rates change, so confirm them with your customs broker or tax adviser.
Is isopropyl alcohol flammable, and what is its UN number?
Yes. The TDS describes IPA as a highly flammable liquid and vapour that causes serious eye irritation. It ships as UN 1219, Class 3 flammable liquid, Packing Group II. Read the Safety Data Sheet before handling; it sets out the fire and handling precautions.
How should isopropyl alcohol be stored?
Store IPA in a cool, dry, well-ventilated place, tightly closed and away from heat and ignition sources. Keep it away from strong oxidising agents and concentrated acids. The SDS calls for non-sparking tools and explosion-proof equipment, and gives a vapour density of 2.07 (air = 1), meaning the vapour is heavier than air.
What are the flash point, boiling point and auto-ignition temperature of IPA?
The flash point of isopropyl alcohol is 12 C (closed cup), its boiling point is 82.5 C at 760 mmHg and its auto-ignition temperature is 399 C. Flammable limits in air are 2.0% to 12.7% by volume. Values are from the Safety Data Sheet and product data.
What is the difference between Technical grade and IP grade IPA?
Technical grade is specified by weight (99.80% w/w minimum, GC); IP grade follows the Indian Pharmacopoeia and is specified by volume (99.0% v/v minimum). IP also lists peroxides, impurities and absorbance limits that Technical does not. The two assay figures are on different bases, so they are not directly comparable. Technical grade is not a pharmacopoeial, food or pharma grade, so for pharmaceutical processing ask for IP grade and let your QA team approve the grade and the batch Certificate of Analysis.
Can British Pharmacopoeia (BP) grade IPA be supplied?
BP stands for British Pharmacopoeia. The IP-grade data sheet notes that BP limits are near-identical to IP and available on request. Please ask before assuming BP supply, and tell us the monograph edition your QA team needs so we can confirm what can be offered.
What is the specification of 99.8% Technical grade IPA?
Per the TDS: assay 99.80% w/w minimum (GC), water 0.10% w/w maximum, non-volatile residue 0.005% w/v maximum, refractive index 1.376 to 1.378 at 20 C (DFPCL basis). On the Deepak Phenolics basis: benzene 2 mg/kg maximum, colour 5 APHA maximum, aldehydes and ketones 0.20% maximum. Confirm figures against the batch Certificate of Analysis.
What is the IP grade specification of isopropyl alcohol?
Per the IP-grade TDS: assay 99.0% v/v minimum, water 0.50% maximum, relative density 0.785 to 0.789, refractive index 1.376 to 1.379, non-volatile residue 20 ppm maximum, benzene 2 ppm maximum, impurities (ex 2-butanol) 0.30% maximum, absorbance at 230 nm 0.30 maximum, peroxides nil.
Which manufacturers are named on SPC's IPA data sheets?
SPC's data sheets name Deepak Fertilisers and Petrochemicals Corporation Ltd (ISO 9001:2015, 70,000 MTPA direct-hydration plant at Taloja, Maharashtra) and Deepak Phenolics Ltd as makers. Deepak Phenolics is the maker named on the IP-grade data sheet.
Is Supreme Petro Chemicals a manufacturer of IPA?
No. Supreme Petro Chemicals is a Chennai importer and bulk distributor, not a manufacturer. We supply IPA as a chemical for ink, coating, electronics, pharma and sanitiser manufacturers, with a batch Certificate of Analysis supplied with every delivery.
What pack sizes are available for bulk isopropyl alcohol?
SPC lists IPA in 200 L MS barrels, 1000 L IBC tanks and bulk road tankers. The Technical-grade TDS also notes maker-filled drums, and the IP-grade TDS says packing is as per order. State the pack you want when you enquire; the exact format is confirmed at the time of quotation.
Which documents come with an IPA order (SDS, TDS, CoA)?
The product page links the Safety Data Sheet, the Technical-grade TDS (SPC-TDS-ALC-001) and the IP-grade TDS (SPC-TDS-ALC-006). A batch Certificate of Analysis is supplied with every delivery. The TDS shows typical limits; the Certificate of Analysis reports the results for the batch delivered.
What is IPA used for in printing inks, electronics cleaning and sanitiser manufacture?
IPA is a fast-evaporating, water-miscible solvent used in printing inks and coatings, electronics and precision cleaning, disinfectant and sanitiser raw material, pharmaceutical processing, cosmetics and extraction. SPC supplies it as a chemical for those manufacturers; the buyer's QA decides which grade suits the process.
Is isopropyl alcohol the same as rubbing alcohol?
In some markets, rubbing alcohol is isopropyl alcohol diluted with water; the exact composition varies by product and country. SPC supplies industrial isopropyl alcohol in Technical and IP grade, not retail rubbing alcohol.
How is IPA different from ethanol and methanol?
IPA has three carbon atoms and is a secondary alcohol; ethanol has two and methanol one. They differ in evaporation rate, toxicity, regulatory control and solvency, so substituting one for another needs your own technical approval.
How do I dilute IPA to 70%?
As general knowledge, dilute with water using C1V1 = C2V2. For 1 litre of 70% v/v from 99.0% v/v IPA, measure about 707 ml of IPA and make up to 1 litre with water. SPC supplies the concentrated Technical and IP grades, not ready-diluted 70%.
Which IPA strength do I need for disinfection and which for solvent use?
As general knowledge, about 70% v/v is commonly used for disinfection, while 99% and above suits solvent duties such as inks, coatings, electronics cleaning and extraction. Always check whether a strength is stated w/w or v/v. SPC lists Technical and IP grade, both concentrated.
Where can I buy bulk IPA in Chennai?
