  • Applications

    (1-(Ethylthio)ethyl methyl disulfide) (CAS 183554-17-8) finds practical use primarily in fragrance and cosmetics, where it is employed as an odorant and fragrance ingredient or fixative in perfumery and personal care formulations. It is also commonly evaluated as a synthetic intermediate for sulfur-containing building blocks used in specialty chemicals, including pharmaceuticals and agrochemicals. In the polymers/plastics sector it may serve as a synthetic precursor for sulfur-containing monomers or as a specialty additive in resin formulations. Additionally, it can be used as an odorant component in cleaning products and has potential as a synthetic intermediate in agricultural chemical development. Actual applications depend on local regulations and formulation limits.
