1. Product Description 

Monopotassium phosphate, MKP, (also potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate), KH2PO4, is a soluble salt of potassium and the dihydrogen phosphate ion which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium. It is also a buffering agent. 

Monopotassium phosphate is produced by the reaction of hot phosphoric acid and potassium hydroxide or extraction of phosphoric acid and potassium hydroxide is the major method of industrial production. The former has high purity and the process is simple. The latter utilizes wet extraction of phosphoric acid with low cost.
