Calcium hydrogen phosphate(CAS: 7757-93-9)

Calcium hydrogen phosphate (CAS: 7757-93-9) is a white, crystalline inorganic compound with the chemical formula CaHPO4·2H2O. It is a calcium salt of phosphoric acid, commonly used as a food additive, pharmaceutical ingredient, and industrial material. The compound is slightly soluble in water and exhibits mild hygroscopic properties, making it suitable for various applications requiring controlled release of calcium or phosphate ions.

Calcium hydrogen phosphate (CAS: 7757-93-9) is widely used in food industry as an emulsifier, stabilizer, and anti-caking agent (E341). It also serves as a source of calcium in dietary supplements and pharmaceuticals, and is employed in industrial processes like detergent manufacturing and flame retardant production. In research, it functions as a buffer and reagent for phosphate-related studies, leveraging its chemical stability and solubility properties.

Calcium hydrogen phosphate (CAS: 7757-93-9) is generally considered safe when used in accordance with regulatory guidelines. It is non-toxic in moderate amounts but may cause mild irritation upon inhalation or skin contact. Safety standards, such as those set by the FDA and OSHA, ensure its use in food and pharmaceuticals is controlled. Proper handling, including PPE and ventilation, minimizes risks during industrial or laboratory applications.

Calcium hydrogen phosphate (CAS: 7757-93-9) should be stored in a cool, dry place (ideally below 25°C), away from moisture and light. Use airtight, sealed containers to prevent hygroscopic degradation. Maintain humidity levels below 60% and store in well-ventilated areas to ensure stability. Avoid exposure to acids or alkalis to preserve its chemical integrity.
