Product: Calcium Hydrogen Phosphate (DCP, CaHPO₄)

CAS No.: 7757-93-9 (Anhydrous) / 7789-77-7 (Dihydrate)
Hazard Class: Non-hazardous
UN No.: Non-regulated
Appearance: White crystalline powder

Description: Calcium hydrogen phosphate is produced through neutralization of phosphoric acid with calcium hydroxide or by precipitation from bone ash, serving as a multi-functional mineral supplement with 23% calcium and 18% phosphorus content. The dihydrate form (food/pharma grade) provides slow nutrient release in animal feed (improves bone density) and tablet excipient (direct compression aid), while anhydrous type (industrial) functions as polishing agent in toothpastes (RDA 70-90) and anticaking additive. Its low solubility (0.02g/100mL water) ensures gradual bioavailability, meeting FAO/WHO specifications (JECFA Monograph 19) for food fortification.
