                                Chemical Name:

                                Monosodium Phosphate  Sodium Dihydrogen phosphate

                                Molecular Formula:

                                NaH2PO4, NaH2PO4·H2O, NaH2PO4·2H2O

                                Molecular Weight:

                                anhydrous: 120.01; Monohydrate: 138.01; Dihydrate: 156.01

                                CAS:

                                anhydrous: 7558-80-7; Monohydrate: 10049-21-5; Dihydrate: 13472-35-0

                                Character:

                                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.

                                Uses:

                                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.

                                Packing:

                                It is packed with polyethylene bag as liner and a compound paper-plastic woven bag as the outer layer. The net weight of each bag is 25kg.
