Calcium acetate hydrate is a white, crystalline powder used as a calcium supplement and in pharmaceutical formulations. It serves as a source of calcium ions in medical and industrial applications. In the laboratory it is used as a buffer component and to precipitate oxalates, and it is permitted as an inert ingredient in non-food pesticide formulations. It is supplied as the hydrate, (CH3CO2)2Ca · xH2O, with a molecular weight of 158.17 g/mol on an anhydrous basis, CAS number 114460-21-8, and stored at ambient temperatures. Signal word: Warning. Molekula supplies Calcium acetate hydrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
