Description
Sodium hydrogen phosphate is used in food and water treatment in conjunction with trisodium phosphate. It is used as an emulsifier and buffer in foods and pharmaceuticals, anti-caking additive in powdered products, dietary supplement, scale inhibitor, reagent and buffer in analytical chemistry. It finds application in detergents, cleaning agents, textile, leather auxiliary, fertilizers and galvanoplastics. Further, it is used as a saline laxative to treat constipation. It inhibits the calcium scale formation in water treatment plants.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
