2,2'-Dipyridyl Disulfide (CAS: 2127-03-9) is a useful reagent for determination of sulfhydryl groups, preparation of amino acid active esters and the thio esters of phosphoric acid. 2,2′-Dipyridyl disulfide is a common reagent in peptide chemistry, it acts as a peptide coupling reagent and as an oxidizing agent, often used in oxidation–reduction condensations to form peptide bonds or in coupling reactions to form disulfide-linked heterodimers. It is also used for the activation of glycosides.
