Ammonium peroxydisulfate, 98%
Description
Ammonium peroxydisulfate is widely utilized as an oxidizing agent and radical initiators in the polymerization of certain alkenes. It is actively involved in in the synthesis of commercially important polymers like styrene-butadiene rubber and polytetrafluoroethylene. It combines with tetramethylethylenediamine to catalyze the polymerization of acrylamide. Due to its oxidizing properties, it can be employed to etch copper on printed circuit boards which is an alternative to ferric chloride solution. Also, it acts as oxidants in organic synthesis.
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.
