Diphenyl disulfide is the chemical compound with the formula (C 6 H 5 S) 2. This colorless crystalline material is often abbreviated Ph 2 S 2. It is one of the more commonly encountered organic disulfides in organic synthesis. Minor contamination by thiophenol is responsible for the disagreeable odour associated with this compound.
Diphenyl sulfide and its analogues can also be produced by coupling reactions using metal catalysts. [5] It can also be prepared by reduction of diphenyl sulfone. [6] Diphenyl sulfide is a product of the photodegradation of the fungicide edifenphos. [7] Diphenyl sulfide is a precursor to triaryl sulfonium salts, which are used as photoinitiators.
It’s the perfect 1:1 swap if you’re currently using one of its best-selling antiperspirants, as this version uses zinc neodecanoate to reduce odor and eliminate odor-causing bacteria. Customer ...

The oxidation and reduction of protein disulfide bonds in vitro also generally occurs via thiol–disulfide exchange reactions. Typically, the thiolate of a redox reagent such as glutathione, dithiothreitol attacks the disulfide bond on a protein forming a mixed disulfide bond between the protein and the reagent. This mixed disulfide bond when ...
Organosulfur chemistry is the study of the properties and synthesis of organosulfur compounds, which are organic compounds that contain sulfur. [1] They are often associated with foul odors, but many of the sweetest compounds known are organosulfur derivatives, e.g., saccharin.
DTT is a reducing agent; once oxidized, it forms a stable six-membered ring with an internal disulfide bond.It has a redox potential of −0.33 V at pH 7. [1] The reduction of a typical disulfide bond proceeds by two sequential thiol-disulfide exchange reactions and is illustrated below.
Diphenyl diselenide is the chemical compound with the formula (C 6 H 5) 2 Se 2, abbreviated Ph 2 Se 2. This yellow-coloured solid is the oxidized derivative of benzeneselenol . It is used as a source of the PhSe unit in organic synthesis .
