Potassium dihydrogen phosphate (MKP)

 

Alias: monopotassium phosphate

CAS No. :7778-77-0

Molecular formula: KH2PO4

MW: 136.08

 

Character: Colorless cubic  crystallization or  white crystal powder,Melting point is 252.6 °C. The relative density is 2.338, and it dissolves in water. Its aqueous solution is acidity. But doesn’t dissolves in ethanol.Heat it up to 400 centirade,  melts and becomes transparent liquid. After efrigerating, it become opaque potassium metaphosphate. And it is easy to deliquesce .

 

Uses: Used as a fertilizer, flavoring agent, brewing yeast culture agent,and used in medicine and manufacturing of  potassium meta-phosphate .
