What is Pyrophosphoric acid CAS 2466-09-3？
Pyrophosphoric acid is a colorless needle shaped crystal or colorless viscous liquid that forms crystals after prolonged storage and is colorless glassy. Pyrophosphate ions have strong coordination properties, and excessive P2O74- can dissolve insoluble pyrophosphate salts (Cu2+, Ag+, Zn2+, Mg2+, Ca2+, Sn2+, etc.) to form coordination ions, such as [Cu (P2O7) 2] 6-, [Sn (P2O7) 2] 6-, etc. It is commonly used as a catalyst in industry to produce organic phosphate esters, etc.
