  • Applications

    Cyclononadec-2-en-1-one (CAS 88642-02-8) is an unsaturated macrocyclic ketone with a clean, slightly sweet, soft musk character, used primarily as a fragrance ingredient in fine fragrances, cosmetics, detergents, and personal care to build musk base notes, enhance substantivity, and act as a fixative; in aroma R&D it serves as a reference/standard for structure–odor relationship studies, GC–O/GC–MS calibration, and sensory evaluation; in organic synthesis it is employed as a starting material or scaffold for preparing other macrocyclic musk derivatives; it is also applied in malodor counteractant testing, modulation of base fragrance profiles, and in quality control and assessor training; use should comply with applicable fragrance usage limits and safety regulations for the target market.
