Description

CAS: 7772-98-7 | Na2O3S2 | 158.10 g/mol

Sodium thiosulfate is used in volumetric analysis to estimate the concentration of certain compounds in solution (hydrogen peroxide) as well as chlorine content in bleaching powder and water. It is used to prepare S-alkylthiosulfonates. Furthermore, it is used in the tanning of leather and in photographic processing. It is used as an antidote to cyanide poisoning and acts as a safe disposal medium in chemistry laboratories when working with bromine, iodine and other strong oxidizers. It is an important component in hand warmers and heating pads.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
