2,2′-Dipyridyl disulfide is a useful reagent for the determination of sulfhydryl groups. 2,2′-Dipyridyl disulfide is a common reagent in peptide chemistry, often used in oxidation–reduction condensations to form peptide bonds or in coupling reactions to form disulfide-linked heterodimers.

体外研究(In Vitro)
Formation of intramolecular S–S bonds can be dramatically accelerated by addition of a 2,2′-Dipyridyl disulfide (2-PDS) solution to an air-oxidized mixture of cysteine-containing peptides. has not independently confirmed the accuracy of these methods. They are for reference only.
