  • Applications

    (1Z,4Z)-germacrene B is a sesquiterpene commonly encountered as a fragrance component in essential oil formulations. In practical use, it may serve as an aroma ingredient in perfumery and flavor formulations, find application in cosmetics and personal care for scent contributions, and be incorporated into household products such as air fresheners. It is often evaluated as a chemical intermediate or building block in industrial fragrance synthesis, and may act as a precursor for further terpenoid elaboration in chemical production. Depending on local regulations and formulation limits, it can also be used as an odorant additive in coatings or inks.
