  • Applications

    Ethyl vinyl disulfide (CAS 24298-49-5) is primarily used as an intermediate in organosulfur chemistry and as a reactive building block for specialty polymers. In industrial manufacturing, it serves as a vinyl-disulfide monomer or functional crosslinking agent to introduce sulfur-containing linkages into polymer networks. It can participate in radical-initiated and thiol-ene type reactions, enabling targeted modification in coatings, adhesives, and inks. Additionally, it is used as a precursor to more complex sulfur-containing compounds and to materials with dynamic disulfide features, with applications pursued under controlled formulations and local regulations.
