Stannous pyrophosphate Usage And Synthesis
Chemical PropertiesWhite Solid
Chemical PropertiesStannous pyrophosphate, Sn2P2O7, sp gr 4.009 at 16 °C (60.8 °F), is an amorphous white powder, decomposing at above 400 °C. It is insoluble in water and soluble in concentrated mineral acids and sodium pyrophosphate.
UsesTin(II) pyrophosphate is used to inhibit the formation of volatile sulfur compounds. Further, it is used for cyanide-free tin coating.
UsesTin(II) Pyrophosphate inhibit the formation of volatile sulphur compounds (VSC).
Production MethodsIt is prepared from stannous chloride and sodium pyrophosphate, and used as a caries preventative in toothpaste and as a diagnostic aid in radioactive bone scanning and red-blood-cell labeling.
Brand nameTechneScan PYP (Mallinckrodt).
