Description and Uses
Citric Acid Monohydrate is a tricarboxylic acid found in citrus fruits. Citric acid is used as an excipient in pharmaceutical preparations due to its antioxidant properties. It maintains the stability of active ingredients and is used as a preservative. It is also used as an acidulant to control pH and acts as an anticoagulant by chelating calcium in the blood. Additionally, Citric Acid Monohydrate is used as an acidulating, food additive, and synergist in antioxidant mixtures.
