CAS No.: 7757-93-9

EINECS No.: 231-826-1

Molecular Formula: CaHPO?

Molecular Weight: 136.06 g/mol (anhydrous); 234.15 g/mol (dihydrate)

Classification: Inorganic compound, calcium phosphate, food additive, pharmaceutical excipient, fertilizer raw material, animal feed additive, fine chemical, analytical reagent

Physical & Chemical Properties

Appearance: White crystalline powder or crystalline solid, odorless, tasteless; stable under normal conditions, incompatible with strong acids and strong bases; non-flammable, non-explosive; slightly hygroscopic; non-irritating under normal use.

Density: 2.306 g/cm3 (anhydrous, 25℃, lit.); 2.30 g/cm3 (dihydrate); LogP: -2.36 (predicted); PSA: 86.28; precise mass: 135.9215 (anhydrous).

Melting Point: 190℃ (decomposes, anhydrous); 109℃ (loses crystal water, dihydrate); decomposes completely at 203℃.

Boiling Point: No obvious boiling phenomenon; decomposes at high temperature to form calcium pyrophosphate.

Solubility: Slightly soluble in water (0.02 g/100mL at 25℃, anhydrous); soluble in dilute hydrochloric acid, nitric acid and acetic acid; insoluble in ethanol and other organic solvents; solubility increases slightly in the presence of carbon dioxide.

Flash Point: Not applicable; Vapor Pressure: Negligible at 25℃; pH Value: 7.4-8.2 (saturated aqueous solution, 25℃); pKa: 7.2 (25℃).

Purity: ≥97.0% (industrial grade); ≥98.0% (food grade); ≥99.0% (pharmaceutical grade, USP/BP); ≥99.5% (high-purity grade).

Storage Condition: Sealed, stored in a cool and dry place at room temperature, protected from light and moisture; keep container tightly closed; avoid contact with strong acids and strong bases; store in a well-ventilated warehouse; separate from incompatible substances.

Main Uses

Food Industry: Used as a food additive (calcium fortifier, leavening agent, stabilizer and emulsifier); added to dairy products, bread, biscuits, beverages and nutritional supplements to supplement calcium and improve product quality.
Pharmaceutical Field: As a pharmaceutical excipient (filler, binder and calcium supplement); used in the preparation of tablets, capsules and oral suspensions; also used as a raw material for calcium supplement drugs to prevent and treat calcium deficiency.
Animal Feed Field: Used as an animal feed additive to supplement calcium and phosphorus for livestock and poultry, promote bone development, improve feed utilization and enhance animal immunity.
Other Fields: Used as a raw material for fertilizers, ceramics and glass; applied in water treatment as a water softener; used as an analytical reagent in laboratory research for the determination of calcium and phosphorus; used in toothpaste formulations to prevent tooth decay.
