  • Applications

    Undec-8-enol (CAS 95008-94-9) is primarily used as an intermediate in the synthesis of fragrance and flavor compounds, serving as a precursor for ester derivatives employed in cosmetics and personal-care products. Due to its hydroxyl group and an internal double bond, it is also considered a building block for other specialty chemicals, including polyols and derivatives for polymers and surfactants. In the field of industrial coatings and inks, it can function as a functional intermediate or additive to adjust film-forming properties and adhesion. Additionally, undec-8-enol may be evaluated as a precursor for other industrial chemicals, depending on the intended use and local regulations.
