Potassium Phosphate, Dibasic, Anhydrous (K2HPO4) is a reagent with a very high buffering capacity. Widely used in molecular biology, biochemistry, and chromatography. Potassium phosphate occurs in several forms: monobasic (KH2PO4), dibasic (K2HPO4), and tribasic (K3PO4).
Also known as potassium dihydrogen phosphate, 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 phosphorous and potassium. It is also a buffering agent.
