    Description

    Applications
    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).

    Solubility
    Soluble in water. Slightly soluble in ethanol.

    Notes
    Loses H{2}O at 400°, forming metaphosphateHygroscopic.
