What is Ammonium persulfate?

Ammonium persulfate is a chemical compound with CAS number 7727-54-0. It is used in various industrial and research applications.

Applications

Ammonium persulfate forms oxygen free radicals in aqueous solution by a base-catalyzed mechanism1. The bases most commonly used as catalysts are tertiary amines such as N,N,N′,N′-tetramethylethylenediamine (TEMED) or 3-dimethylaminopropionitrile (DMAPN). The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix, which can be used for separating macromolecules by size.
