  • Applications

    3-Methyl-4-ccyclopentadecen-1-one (CAS 36399-15-2) is a macrocyclic musk ketone widely used in perfumery as a musk note and a fragrance fixative to extend scent longevity in fine fragrances and related consumer products. It is also employed in cosmetics/personal care as a fragrance ingredient to impart a lasting musk character. In household products such as air fresheners, detergents, and cleaners, it contributes a musk note to enhance product perception. In fragrance chemistry and industrial formulation, it may serve as an intermediate or building block for synthesizing related musk compounds, and can be incorporated into coatings, inks, and plastics formulations as a fragrance additive subject to formulation limits.
