  • Applications

    Cedrenone (CAS 30960-39-5) is principally considered a fragrance ingredient with cedar-like notes and is used in perfumery and personal-care formulations, where it may function as an odorant and, in some formulations, as a fragrance fixative or scent modifier; it can also serve as a starting material or intermediate for the synthesis of other fragrance compounds. In industrial contexts, it may be evaluated as a building block for fragrance chemistry or as an aroma additive in household products and cleaners to impart cedar-like notes. Some applications may extend to coatings or inks where scent is a design feature, subject to formulation limits and local regulations.
