2,2'-Dipyridyl disulfide is a versatile organosulfur compound widely used in peptide synthesis and biochemical research. This compound exhibits a melting point of 56-58°C and boiling point of 356.1±17.0°C at 760 mmHg. With a density of 1.3±0.1 g/cm³ and flash point of 169.2±20.9°C, it serves as an important thiol-disulfide exchange reagent. The material should be stored in sealed containers at room temperature, protected from light. Safety precautions include wearing protective gloves and eye/face protection due to potential irritation (GHS Category 2). Its unique structure makes it valuable for protein modification and as a coupling agent in organic synthesis.
