  • Applications

    Undeca-1,5-dien-3-ol (CAS 56722-23-7) is primarily used as a chemical building block in fragrance and flavor chemistry, serving as an intermediate for synthesizing aroma compounds and scent precursors. It also appears in cosmetics and personal care formulations as a fragrance ingredient or as a component in fragrance blends. In materials science, it functions as a versatile building block for specialty polymers and copolymers and as a reactive precursor in coatings and inks where its alkenyl and hydroxyl functionalities permit further chemical modification. Additionally, it may serve as a processing intermediate in the synthesis of other specialty chemicals within general industrial manufacturing. Use is subject to local regulations and formulation limits.
