  • Applications

    Pinacolyl alcohol (CAS 464-07-3) is primarily used as a chemical intermediate in organic synthesis, notably for the production of pinacolone and related ketones; it can function as a solvent or processing aid in industrial manufacturing; it serves as a building block for fragrance ingredient synthesis in the perfumery industry; it may be used as a reactive intermediate or precursor for specialty polymers and plastics; and it is encountered as a component in coatings and inks formulations as a solvent or processing aid. Subject to local regulations and formulation limits.
