  • Applications

    Anastreptene is primarily used as an odorant in perfumery, serving as a fragrance ingredient. It is also employed as a fragrance component in cosmetics/personal care products and in household cleaning formulations to impart a characteristic aroma. In industrial manufacturing, it is commonly used as an intermediate or building block in the synthesis of more complex fragrance compounds. Depending on local regulations and formulation limits, its use may be considered across fragrance-related applications.
