Frequently Asked Questions
What is glacial acetic acid? Is it the same as ethanoic acid?
Yes — acetic acid and ethanoic acid are the same chemical; ethanoic acid is the IUPAC name. Glacial acetic acid (GAA) is the water-free, full-strength form. Our glacial material assays 99.85% w/w acetic acid minimum and solidifies around 16.6 °C in cold weather, which is why it is called "glacial".
What is the CAS number and HSN code of acetic acid?
The CAS number is 64-19-7 and the HSN code is 2915 21 00. For transport it ships as UN 2789, Class 8 corrosive, Packing Group II.
What is acetic acid used for?
Buyers use it in textile processing, as vinyl acetate and PTA feedstock, for rubber coagulation, food acidity regulation, pharmaceutical synthesis and acid cleaning. It is a clear, colourless liquid with a pungent vinegar-like odour, miscible with water, ethanol, ether and glycerine.
Which grades of acetic acid do you stock, and does the glacial grade meet IS 695?
We stock industrial, technical, glacial and food grades. Our glacial material is sourced from GNFC (BIS-licensed, CM/L-7200188009) and conforms to IS 695 : 2020 Pure Grade with 99.85% w/w minimum acetic acid content on the COA. That glacial material is not food-grade — food grade is a separate stocked grade, so tell us your application when you enquire.
Is glacial acetic acid corrosive?
Yes. It is a Class 8 corrosive liquid (UN 2789, Packing Group II) and also flammable, with a flash point of 39 °C (closed cup). Vapours and liquid are dangerous to eyes and skin — wear chemical goggles and resistant gloves, and store it cool, well-ventilated and away from oxidisers.
Where can I buy glacial acetic acid in Chennai, and what packaging do you supply?
We stock it at our Redhills, Chennai warehouse and dispatch across South India. Packaging runs from 30 kg HDPE carboys and 200 L HDPE barrels to 1000 L IBC tanks and bulk tankers; order sizes depend on packaging and current stock.
