Uses
Diphenyl disulfide is a versatile organic sulfur compound, mainly used as a pharmaceutical intermediate in the synthesis of anti-HIV drugs (e.g., Nelfinavir) and other bioactive molecules. It serves as a key reagent for introducing phenylthio groups in organic synthesis, acting as a catalyst for photoisomerization of alkenes and a vulcanization accelerator in the rubber industry. It is also applied in organic photoelectric material modification, lithium battery additives, and as a laboratory reagent for radical reaction research.
