Mono Calcium Phosphate (MCP) is a calcium phosphate salt widely used as a nutritional supplement, acidulant, and leavening agent in food processing, as well as a phosphate source in pharmaceuticals and animal feed. It is also employed in ceramics and as a buffering agent in various industrial applications. Mono Calcium Phosphate (CAS 10031-30-8) has the molecular formula Ca(H₂PO₄)₂·H₂O with a molecular weight of 252.07 g/mol. It is stored at ambient conditions but requires careful handling due to its Danger classification under GHS.
Molekula supplies Mono Calcium Phosphate at ≥95% purity (dried basis) in 1 kg packs, from £61.20 inc. VAT. It is in stock for same-day dispatch. Every batch ships with a certificate of analysis, and safety data sheets are available in 6 languages. Larger quantities, up to multi-tonne, are quoted on request.
