  • Applications

    2-(Methylthiomethyl)-3-phenyl-2-propenal, (2E)- (CAS 65887-08-3) is an alpha,beta-unsaturated aldehyde derivative primarily used as a fragrance intermediate; in practice it may be employed as a fragrance ingredient in perfumery and cosmetics, as a flavor/aroma precursor in food-oriented applications, and as a chemical building block in industrial manufacturing for the synthesis of thioether-containing aroma compounds; it may also be used in household products such as air fresheners as part of odor formulations; and researchers may evaluate it as a synthetic intermediate for specialty aroma compounds.
