Calcium Acetate is a calcium salt of acetic acid. Calcium is a mineral essential for many cellular functions including nerve impulse transmission, muscle contraction, cardiac function, bone formation, and capillary and cell membrane permeability. Calcium acetate is administered orally to prevent or treat calcium deficiency and to treat hyperphosphatemia due to its phosphate-binding properties.The chemical compound calcium acetate is the calcium salt of acetic acid. It has been commonly referred to as the acetate of lime. The anhydrous form is very hygroscopic, therefore the monohydrate is the common form.

1. Used as a food stabilizer, chelating agent, mold inhibitor, buffer, flavor enhancer, and corrosion inhibitor. Calcium acetate is also an excellent food calcium fortifier, with better absorption than inorganic calcium.It may be used in infant foods at a level of 6.0–33.0 g/kg (calculated as elemental calcium, the same below); and in cereals and cereal products at 1.6–3.2 g/kg.

2. Used in the production of acetone, acetic acid, and the polyester industry; also used in the synthesis of acetates.

3. Used as an analytical reagent.
