Calcium gluconate anhydrous is a stable calcium salt derived from gluconic acid, widely used in pharmaceuticals as a dietary supplement to treat calcium deficiencies and hypocalcemia, and in the emergency treatment of hyperkalemia and hydrofluoric acid burns. It’s also employed in food and beverage fortification, animal feed, and industrial applications requiring calcium supplementation. This anhydrous form has a CAS number of 299-28-5, a molecular formula of C12H22CaO14, and a molecular weight of 430.37. It is non-hazardous (signal word: None) and stores safely at ambient conditions.
