  • Applications

    1-Dehydro-(8)-gingerdione (CAS 748159-34-4) is primarily encountered as an aroma-related intermediate used in fragrance chemistry to provide ginger-like notes and as a building block for synthesizing related aroma compounds; in perfumery and cosmetics/personal care it can function as a scent component, while in the flavor industry it may be evaluated as a flavoring intermediate or enhancer of spice profiles; in household products and cleaning formulations it provides characteristic spicy/gingery odor; in industrial manufacturing it is often utilized as a precursor for the synthesis of more complex aroma materials, subject to local regulations and formulation limits.
