Product Category: Industrial Chemicals / Food & Process Chemicals
Chemical Name: Citric Acid Anhydrous
CAS Number: 77-92-9
Chemical Formula: C₆H₈O₇
Molecular Weight: 192.12 g/mol
Appearance: White or colourless crystalline powder or granules
Product Overview
Citric Acid Anhydrous is the water-free form of citric acid and is widely used as an acidulant, pH-control agent, chelating agent, cleaning ingredient and chemical raw material.
Compared with the monohydrate form, the anhydrous product contains significantly less moisture and is often preferred where the formulation requires reduced water contribution.
