Description

Loses H2O at 400°C, forming metaphosphate

Potassium dihydrogen phosphate is used as a food additive, fertilizer (NPK), paint additive, coating additive, adhesive, buffering agent and in optical modulators. It is extensively used in research and analytical laboratories as a buffer in mobile/sample preparations for analysis by high pressure liquid chromatography (HPLC) and also in organic synthesis. MKP, monopotassium phosphate, owing to its non-linear optical properties, is used in optical modulators and for second-harmonic generation (SHG).

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
