Product Name:Tin(II) Fluoride
English Name:Tin(II) Fluoride
CAS No.:7783-47-3
Aliases:Stannous Fluoride, Tin Difluoride
Molecular Formula:SnF2
Physical Properties:White to off-white crystalline powder; melting point approximately 213–215°C, boiling point approximately 850°C, density 4.57 g/cm³. Soluble in water with slow hydrolysis; slightly soluble in ethanol and diethyl ether; soluble in dilute hydrochloric acid and dilute nitric acid.
Uses:Primarily used as an anti-caries active ingredient in toothpaste formulations, it inhibits oral bacterial acid production, reduces dental plaque, and promotes enamel remineralization. It also serves as a mild reducing agent in organic synthesis and is used in metal surface treatment, electroplating, and the preparation of other tin-containing compounds.
