Sodium phosphate is a reagent with very high buffering capacity that is widely used in molecular biology, biochemistry, and chromatography. Sodium phosphate occurs in several forms: monobasic (NaH2PO4), dibasic (Na2HPO4), and tribasic (Na3PO4). Most neutral sodium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.
Application Notes
