Potassium peroxydisulfate, 97%

Description

CAS: 7727-21-1 | K2O8S2 | 270.309 g/mol

Potassium peroxydisulfate is used as an oxidizing agent in organic synthesis. It is involved in the Elbs persulfate oxidation of phenols and the Boyland-Sims oxidation of anilines. In solution, it gives radicals and is used to initiate polymerization reactions to prepare styrene-butadiene rubber and polytetrafluoroethylene. It is used as a bleaching agent in various hair bleaches, as an ion exchange agent, a plating agent and a surface treating agent.

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.
