About this item

IUPAC name	potassium;dihydrogen phosphate
canonical smiles	OP(=O)(O)[O-].[K+]
inchi	InChI=1S/K.H3O4P/c;1-5(2,3)4/h;(H3,1,2,3,4)/q+1;/p-1
inchi key	GNSKLFRGEWLPPA-UHFFFAOYSA-M
molecular formula	KH2PO4
synonyms	Potassium dihydrogen phosphate 7778-77-0 Potassium phosphate monobasic MONOPOTASSIUM PHOSPHATE Monobasic potassium phosphate
Compound Description	Potassium dihydrogen phosphate is a potassium salt in which dihydrogen phosphate is the counterion. It has a role as a fertilizer. It is a potassium salt and an inorganic phosphate. Monopotassium phosphate, MKP, , KH2PO4, is a soluble salt of potassium and the dihydrogen phosphate ion. It is a source of phosphorus and potassium as well as a buffering agent. It can be used in fertilizer mixtures to reduce escape of ammonia by keeping pH low.
