  • Applications

    1,5-Cyclododecadiene, 9-methoxy-1,6,10-trimethyl- (CAS 900779-74-0) finds applications as a building block in fragrance chemistry and as an aroma intermediate in cosmetics; it may serve as an odorant or a fixative in perfumery to influence scent volatility and longevity. It is also considered a specialty monomer or intermediate for the synthesis of fragrance-related compounds and for certain polymer/resin formulations in plastics and coatings. In coatings and inks, it can function as a reactive monomer or modifier to tailor film properties and scent characteristics. It may also be used in household product formulations as a fragrance component, subject to regulatory constraints. Overall, the material is typically employed as an intermediate/building block rather than a bulk ingredient.
