About this product
Citric acid anhydrous (CAS 77-92-9) is the water-free crystalline form of citric acid — a white, odourless powder assaying 99.5–100.5% to the harmonised BP/USP/FCC monograph, known in food applications as additive E330. Buyers use it across food, pharmaceutical, and technical formulations in Technical, Food (FCC), and Pharma (IP/BP/USP) grades. We import from Shandong Ensign (ISO 9001 / FSSC 22000 certified, Kosher and Halal approved), hold stock at our Redhills, Chennai warehouse, and dispatch across South India in 25 kg HDPE-lined paper bags.

Frequently Asked Questions
What is citric acid anhydrous and what is its CAS number?
Citric acid anhydrous (CAS 77-92-9) is the water-free crystalline form of citric acid — IUPAC name 2-hydroxypropane-1,2,3-tricarboxylic acid, designated food additive E330. It is a white, odourless crystalline powder with a strong sour taste, used across food, pharmaceutical, and technical formulations.
What is the difference between citric acid anhydrous and monohydrate?
Anhydrous is the water-free form of citric acid (CAS 77-92-9), while the monohydrate (CAS 5949-29-1) crystallises with one molecule of water. Both are white crystalline powders that are freely soluble in water. We stock both forms at our Redhills, Chennai warehouse — see our Citric Acid Monohydrate page for that grade.
What grades of citric acid anhydrous do you supply?
We stock Technical, Food grade (FCC), and Pharma (IP/BP/USP) grades. Our imported material is produced by Shandong Ensign — ISO 9001 / FSSC 22000 certified, Kosher and Halal approved — and assays 99.5–100.5% against the harmonised BP/USP/FCC monograph.
Is citric acid anhydrous hazardous, and how should it be stored?
It is a mild skin and eye irritant but is not classified as dangerous goods for transport and carries no UN number. Store in a cool, dry area below 25°C and keep bags tightly closed — the product is hygroscopic and can cake if exposed to moisture. Shelf life is 24 months from manufacture.
What is the HSN code for citric acid anhydrous?
Citric acid anhydrous is classified under HSN code 2918 14 00. We supply every consignment with TDS and MSDS documentation.
Can I buy citric acid anhydrous in bulk in Chennai?
Yes. We import citric acid anhydrous, hold stock at our Redhills, Chennai warehouse, and dispatch across South India — typically ex-stock to 3 working days. Standard packing is 25 kg HDPE-lined paper bags; order sizes depend on packaging and current stock, so call or WhatsApp +91 86087 80096 for a quote.
