  • Applications

    Ethenol, 2-phenyl-, 1-acetate (CAS 1566-67-2) is viewed as an organic synthesis intermediate and as a reactive monomer precursor for specialty polymers and coatings, enabling the incorporation of phenyl and acetate functionalities into copolymers and adhesives. It can function as a processing aid or reactive diluent in coatings and inks, and may serve as a precursor to fragrance-related esters in perfumery. It is also evaluated for use in adhesive formulations and as a building block for specialty solvents in industrial manufacturing, with use limited by local regulations and formulation constraints.
