  • Applications

    Chemical name: 3-Heptenyl 2-methyl propanoate, (3E)-; CAS number: 207801-32-9 is an ester primarily used as a fragrance ingredient and as an intermediate in the synthesis of aroma compounds. In practice, it is evaluated for applications in perfumery to yield green and fruity notes, and it can serve as a precursor for other aroma esters. It may also be considered for flavor formulation and in cosmetics/personal care as an odorant component, with potential use in household products and in coatings or inks as a fragrance additive. Additionally, it can function as a building block in industrial manufacturing of related aroma chemicals. Use is subject to local regulations and formulation limits.
