Monocalcium phosphate monohydrate

Monocalcium phosphate monohydrate (CAS 10031-30-8), commonly abbreviated as MCP, is a calcium phosphate salt used as a leavening acid, acidulant, and pH regulator across food and pharmaceutical applications. Calcium superphosphate is a recognized commercial term for related phosphate fertilizer grades sourced through agricultural supply channels. In baked goods, MCP acts as a fast-acting leavening acid.

It reacts with sodium bicarbonate to produce CO₂ during mixing, giving formulators precise control over dough rise and texture. Food manufacturers incorporate it as an acidulant and buffering agent. It is used in processed cheeses, meat products, and beverage formulations where controlled pH is critical to shelf life. In pharmaceutical manufacturing, it functions as a calcium source and excipient.

It is frequently utilized in tablet and mineral supplement formulations. Agricultural buyers source MCP as a soluble phosphorus fertilizer component, particularly in fertigation systems and compound production. Monocalcium phosphate monohydrate is available as a white crystalline powder or granule. Standard grades include food-grade (FCC), feed-grade, and technical-grade for various industrial uses.

Food applications typically requiring FCC-compliant material ensure high purity and safety. Bulk supply is common for industrial and agricultural buyers, with smaller packaging available for specialty use.
