General description

Potassium phosphate dibasic is a useful biological buffer having a pH in the range of 8.5–9.6. Potassium phosphate is present in various forms: monobasic (KH2PO4), dibasic (KH2PO4), and tribasic (K3PO4). Potassium phosphate buffers are widely employed in equilibrium dialysis, high performance liquid chromatography (HPLC) and affinity capillary electrophoresis studies.
