Calcium hydrogen phosphate dihydrate

Description:
Calcium hydrogen phosphate dihydrate, with the chemical formula CaHPO₄·2H₂O and CAS number 7789-77-7, is an inorganic compound commonly used in various applications, including as a dietary supplement and in fertilizers. It appears as a white crystalline powder and is relatively soluble in water, which facilitates its use in biological systems. The compound is characterized by its ability to provide calcium and phosphate ions, essential for bone health and metabolic processes. It has a molar mass of approximately 172.18 g/mol and typically forms in a dihydrate state, meaning it contains two molecules of water for each formula unit. Calcium hydrogen phosphate dihydrate is stable under normal conditions but should be stored in a dry environment to prevent degradation. Its pH in solution is generally neutral to slightly acidic, making it compatible with various biological environments. Additionally, it is non-toxic and considered safe for use in food and pharmaceutical applications, contributing to its widespread use in nutritional supplements and as a food additive.
