Overview
2,2'-Dipyridyl disulfide is a pyridyl disulfide reagent for thiol-, sulfhydryl-, and disulfide-exchange chemistry. It is also known as 2,2'-dithiodipyridine, Aldrithiol-2, bis(2-pyridyl) disulfide, and 2PDS; the abbreviation 2,2'-DTDP is also used in the literature.
CH58001 is listed with CAS 2127-03-9, molecular formula C10H8N2S2, and molecular weight 220.31. It is used in R&D chemistry centered on pyridyl disulfide reactivity, sulfhydryl assay design, and disulfide-trapping studies.
Applications
- Thiol and sulfhydryl assays: used in literature involving 2,2'-DTDP / pyridyl disulfide chemistry for sulfhydryl-focused assay design.
- Disulfide-trapping work: relevant when disulfide exchange or thiol-reactive capture is part of the chemistry being studied.
- Pyridyl disulfide chemistry: a compact heterocyclic disulfide reagent in studies that reference 2PDS, Aldrithiol-2, or related naming.
