  • Applications

    6,9-Pentadecadien-2-one, (Z,Z) (CAS 78405-86-4) is primarily encountered as an odor-active intermediate in fragrance chemistry and may function as a fragrance ingredient or aroma precursor in perfumery and cosmetics. It is commonly considered for use in household products and air-freshening formulations as a scent component. In industrial manufacturing, it can serve as a building block or intermediate in the synthesis of other organic compounds, including specialty fragrances. It may also be explored as a fragrance additive in coatings, inks, and cleaning formulations, within formulation limits and regulatory constraints.
