Mono Calcium Phosphate (MCP) — Ca(H₂PO₄)₂ or CaH₄(PO₄)₂·H₂O — is a high-purity calcium phosphate compound supplied by Ceramat Private Limited.
It is a white, odorless, and stable powder, slightly soluble in water but readily soluble in dilute acids such as hydrochloric, nitric, and acetic acid. MCP is widely used in pharmaceuticals, food fortification, animal feed, and chemical industries due to its excellent bioavailability and stability.
