Usage And Synthesis

Chemical Properties

Stannous fluoride is a white crystalline solid with a bitter, salty taste.

Chemical Properties

white crystals or powder

Uses

Dental caries prophylactic.

Uses

Stannous fluoride (SnF2) is used as a toothpaste additive to help prevent tooth decay.

Uses

Tin(II) fluoride is used in the prevention of dental caries. It is an active ingredient in toothpastes.

Definition

ChEBI: Stannous fluoride is an inorganic fluoride salt.

General Description

White crystalline solid. Sinks and mixes with water.

Air & Water Reactions

Water soluble.

Reactivity Profile

Tin(II) fluoride, a strong reducing agent, is incompatible with oxidizers. Avoid contact with acids - HF fumes may be produced [USCG, 1999].

Hazard

Toxic by ingestion, strong irritant to skin and tissue.

Health Hazard

EYES: Severe irritation - corrosive, irreversible. SKIN: Corrosive on abraded skin, no effect on intact skin.

Flammability and Explosibility

Not classified

reaction suitability

core: tin
reagent type: catalyst

Biological Activity

The wild type human brahma-related gene 1 (Brg1) encodes a protein of 1,647 amino acids th at contains a conserved domain of the SWI2/SNF2 family necessary for normal mitotic growth and transcription regulation. BRG1 is an essential component of the SWI/SNF chromatin remodeling complexes and implicated in multiple functions through its interaction with different proteins, including the tumor suppressor protein pRb, serine-threonine kinase LKB1, and other transcription factors. Although Brg1 is involved in chromatin remodeling as a complex with other SWI/SNF proteins, purified BRG1 itself is capable of remodeling mono-nucleosomes and nucleosomal arrays in vitro. Mutations of Brg1 have been found in multiple tumor cell lines.

Safety Profile

Poison by ingestion and intraperitoneal routes. Questionable carcinogen. Mutation data reported. When heated to decomposition it emits toxic fumes of F-. See also TIN COMPOUNDS.

Potential Exposure

Stannous fluoride is used in dental caries (tooth decay); as an ingredient of cavity-preventing toothpastes.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN2923 Corrosive solids, toxic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, 6.1Poisonous material, Technical Name Required

Incompatibilities

A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Reacts with acids, forming hydrogen fluoride fumes. Reacts violently with chlorine and metal nitrates. Reacts with metals releasing flammable hydrogen gas.
