  • Applications

    Pent-2-en-3-ol (CAS 38553-82-1) is typically used as an intermediate in organic synthesis, serving as a building block for fragrance and flavor compound production and as a reactive precursor in polymer and resin formulations; it can also function as a specialty solvent or processing aid in industrial manufacturing, and its alkenyl–hydroxyl functionality enables further derivatization for coatings, inks, and related materials.
