Chemical Structure
Sodium trimetaphosphate
Synonym(s): Trisodium cyclo-triphosphate
- CAS No.: 7785-84-4
- Formula:Na3P3O9
- Molecular Weight:305.89
InChIKey: IWMQIKSHQGUPFR-UHFFFAOYSA-N
SMILES: [Na][Na].[Na]P(P(=O)=O)(OO[O])(O[O])P(=O)=O
Biological Activity: Sodium trimetaphosphate (Trisodium cyclo-triphosphate) is an orally active, multifunctional compound. Sodium trimetaphosphate serves as a buffer and chelating agent in cosmetics, a starch modifier in food, and can also act as a bone imaging agent. Sodium trimetaphosphate undergoes alkaline hydrolysis, with the rate-limiting first step producing sodium tripolyphosphate; the conversion rate is low when sodium carbonate or silicate is used. Sodium trimetaphosphate can be used in caries-related research[1][2][3][4][5].
