Sodium dihydrogen phosphate dihydrate  CAS 13472-35-0 is a colorless to white crystalline or crystalline powder. Relative density 2.04, melting point 60 ℃. Heating below 100 ℃, soluble in crystalline water to form a monohydrate (NaH2PO4 · H2O); When continuously heated at 100 ℃, it loses crystalline water and becomes anhydrous; Generate sodium pyrophosphate at 190-210 ℃; Decompose into metaChemicalbook sodium phosphate at 280-300 ℃. Easily soluble in water, with a solubility of 12.14% at 25 ℃ and insoluble in ethanol. It has hygroscopicity and can clump in humid air. The aqueous solution is acidic, with a pH of 4.1 to 4.7 in 1% aqueous solution. Rats were intraperitoneally injected with LD50250mg/kg, and the oral LD50 of rats was greater than 8290mg/kg.
