  • Applications

    11,12-Dihydrolactaroviolin (CAS 24687-70-5) may function as an odorant or fragrance intermediate in perfumery and cosmetics; it can be used as a fixative or scent component in fragrance formulations. It may also be evaluated for inclusion in household products such as air fresheners as a fragrance ingredient; in industrial manufacturing, it may serve as an organic intermediate or processing aid in chemical syntheses. In polymers/plastics formulations, it may act as a processing aid or stabilizer; in coatings and inks, it could function as a specialty odorant or additive to influence aroma. It may also be considered for cleaners where fragrance performance is relevant. All uses are subject to local regulations and formulation limits.
