Dipotassium hydrogen orthophosphate trihydrate

Potassium phosphate is a reagent with high buffering capacity. It occurs in several forms: monobasic, dibasic and tribasic. Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.


  • Component of Culture media
  • Component in phosphate buffered saline


Potassium phosphate dibasic is widely used in molecular biology, biochemistry, and chromatography. It is typically used as a component for a wide variety of media used in the culture of microorganisms, also as a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate.


Soluble in water(100 mg/ml); Insoluble to slightly soluble in ethanol; insoluble in alcohol.
