Citric Acid Monohydrate

Citric Acid Monohydrate is a white or colorless crystalline powder or crystals with a strongly acidic taste. Chemically, it is a tricarboxylic acid with the formula C6H8O7·H2O, naturally found in citrus fruits. It is highly soluble in water and freely soluble in ethanol, and it possesses low reactivity and good chemical stability at ambient temperatures.

It is widely used as an acidulant, flavor enhancer, preservative, and chelating agent in food, pharmaceutical, cosmetic, and chemical industries. It functions as an acidification agent, buffering agent, chelating agent, pH regulator, and stabilizer. Citric Acid Monohydrate is non-toxic, biodegradable, and commonly used in pharmaceutical preparations due to its antioxidant properties, maintaining the stability of active ingredients. It also acts to control pH and can chelate calcium in blood, serving as an anticoagulant. The compound exists as a monohydrate, meaning it contains one molecule of water per molecule of citric acid.​
