  • Applications

    Chemical name: 13-Methyl-1-oxacyclopentadec-10-en-2-one; CAS 329925-33-9 is a macrocyclic lactone that can be used as a fragrance intermediate in perfumery, where it may serve as an aroma component and/or fixative due to the long-lasting scent of the macrocyclic ring. It may also be evaluated for use as an aroma component in flavor formulations under appropriate regulatory controls. In cosmetics and personal care, it can function as a fragrance constituent within products such as creams and lotions. In industrial manufacturing, it can act as an intermediate in organic synthesis, enabling transformations to related lactones or chiral building blocks. As a macrolactone, it may be explored as a monomer or precursor for specialty polyesters or related polymers, and could be considered as a fragrance additive or process aid in coatings or inks, subject to formulation development and regulation.
