              Monosodium Phosphate

              Product Image
              Product Name Monosodium Phosphate
              Molecular formula NaH2PO4,NaH2PO4·H2O,NaH2PO4·2H2O
              Molecular weight anhydrous: 120.01; Monohydrate: 138.01; Dihydrate: 156.01
              CAS NO. anhydrous: 7558-80-7; Monohydrate: 10049-21-5; Dihydrate: 13472-35-0
              Performance It is colorless column crystal, odorless, slightly deliquescence. The relative density is 2.04 and melting point is 60℃. It is easily soluble in water but insoluble in ethanol. If heated below 100℃, it can dissolve in crystal water and convert to monohydrate salt. When heated to 100℃, it will lose crystal water and change to anhydrous substances, which will become sodium metaphosphate if continue to be heated.
              Use In food industry, it is used as buffering, character improving agent, emulsifier, nutrition supplement, antioxidant additive, brine penetrable agent, sugar clarifier, stabilizer, coagulant, fowl scalding agent.
