Application

Sodium Phosphate Monobasic Dihydrate is a versatile reagent primarily utilized for its excellent buffering capacity in a range of applications, from molecular biology, biochemistry, and chromatography to various industrial and pharmaceutical processes. It acts as an acidity regulator and sequestrant in food products like baking powders, and is used as a pH buffer in solutions such as fleet enema, electroplating baths, and acid cleaners. Additionally, it serves as an emulsifier, laboratory reagent, metal phosphating reagent, and as an auxiliary in textile dyeing and printing. This compound is also employed in treating boiled water and wastewater, removing halogens from waste gases, and as a nutritional supplement in cattle feed and other food products. Moreover, it finds roles in dentifrice formulations, vitreous enamel frits, pharmaceutical synthesis, and as a phosphate source for microorganisms in effluent treatment. In therapeutic contexts, Sodium Phosphate Monobasic Dihydrate is used as a mild saline laxative and in treating hypophosphatemia. It is highly valued in high-risk applications for its low microbial and endotoxin limits.
