Calcium acetate monohydrate is a white, crystalline salt composed of calcium, acetic acid, and water, primarily used as a food additive (E263), a buffering agent in pharmaceuticals, and in industrial applications like concrete admixtures to accelerate setting. Laboratories also use it to precipitate oxalates, and it is permitted as an inert ingredient in non-food pesticide formulations. It also serves as a source of calcium in animal feed and as a de-icing agent in cold climates. This chemical has a CAS number of 5743-26-0, a molecular formula of Ca(CH3CO2)2 · H2O, and a molecular weight of 176.18. It is stable at ambient storage conditions with no signal word classification. Molekula supplies calcium acetate monohydrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
