Pyrophosphoric acid has been shown to enhance the rate of pyrophosphate hydrolysis by nonenzymatic catlysis and by inorganic pyrophoshatase. Pyrophosphoric acid can be used for the preparation of vanadyl pyrophosphato methoxide cluster anion. Pyrophosphoric Acid is used in anion binding of inorganic phosphates due to its ability to form complexes.An enhanger of the rate of pyrophosphate hydrolysis by nonenzymatic catlysis and by inorganic pyrophoshatase.
