Description
CALCIUM CITRATE SALT
Mono • Di • Tri • Anhydrous | IP • BP • USP • LR • AR Grades
Calcium Citrate is the calcium salt of citric acid, available in four forms Monocalcium Citrate, Dicalcium Citrate, Tricalcium Citrate, and Anhydrous. It is a white, odourless, fine crystalline powder that is sparingly soluble in water and exhibits a mildly acidic to neutral pH in solution. Aaru Life Science supplies Calcium Citrate in multiple pharmacopoeial and laboratory grades including IP, BP, USP, LR, and AR, ensuring suitability across a wide range of pharmaceutical, food, analytical, and industrial applications. Each batch is manufactured under strict quality control and is compliant with the respective pharmacopoeial standards, making it a reliable choice for formulators, researchers, and industrial users alike.
