  • Applications

    Ethyl Vinyl Sulfide (CAS 627-50-9) is a reactive intermediate used in organic synthesis to introduce thioether and vinyl functionality, enabling construction of sulfur-containing intermediates for pharmaceuticals and agrochemicals. It is used as a monomer or co-monomer in specialty polymers and coatings to impart sulfur-containing backbones and surface functionality. In fragrance applications, it may function as a fragrance intermediate or odor precursor, subject to regulatory controls. Additionally, it is encountered as a platform chemical in research and development for exploratory synthesis of sulfur-containing compounds.
