Potassium peroxydisulfate, ACS, 99.0% min

Description

A Polymerization Accelerant For PAGE Gels. | CAS: 7727-21-1 | K2O8S2 | 270.309 g/mol

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