  1. Product Detail

    Pyrophosphoric acid




    Pyrophosphoric acid is a colorless and viscous liquid.it crystallized into colorless glassy if put it for a long time.



    Pyrophosphate has highly ligancy,usually use it to analytical reagent ,such as masking agent to get organophosphate ester.It is used in pharmaceutical as a solvent .

    It can be used to adjust PH value on the electroplating solution on the plating process.it also can be treat as catalyst,stabilizer on the organic peroxide and metal refining.
