Product Description
Potassium phosphates are inorganic salts based on potassium and phosphate, available in three main commercial forms depending on the K:P ratio.
The three forms and their CAS:
Monopotassium phosphate (MKP, KH₂PO₄) — CAS 7778-77-0
Dipotassium phosphate (DKP, K₂HPO₄) — CAS 7758-11-4
Tripotassium phosphate (TKP, K₃PO₄) — CAS 7778-53-2
All are white crystalline powders, fully water-soluble, serving as efficient phosphorus–potassium nutrient sources and buffering/chelating agents.
Used in food additives, fertilizers, chemical reagents, and water treatment
