Stannous pyrophosphate Chemical Properties,Usage,Production

Chemical Properties

White Solid

Chemical Properties

Stannous 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.

Uses

Tin(II) pyrophosphate is used to inhibit the formation of volatile sulfur compounds. Further, it is used for cyanide-free tin coating.

Uses

Tin(II) Pyrophosphate inhibit the formation of volatile sulphur compounds (VSC).

Production Methods

It 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 name

TechneScan PYP (Mallinckrodt).
