Calcium acetate | C4H6O4.Ca - PubChem

Calcium acetate is the calcium salt of acetic acid. It is used, commonly as a hydrate, to treat hyperphosphataemia (excess phosphate in the blood) in patients with kidney disease: the calcium ion coines with dietary phosphate to form (insoluble) calcium phosphate, which is excreted in the faeces. It has a role as a chelator.
