  • Applications

    2-Ethyl-6-vinylpyrazine (CAS 32736-90-6) is primarily used as an aroma compound in perfumery and flavor applications, delivering nutty, roasted, and savory notes characteristic of pyrazines; it can serve as a chemical intermediate in fragrance and flavor synthesis; it is used in cosmetics/personal care and household products as a fragrance ingredient; it can be incorporated into coatings, inks, and other industrial formulations as a scent additive; and it may be evaluated for use in polymer or plastics contexts as a functional monomer or precursor for scent-release or aroma-modified materials.
