  • Applications

    2-Chlorobenzyl alcohol (CAS 17849-38-6) is primarily used as an organic intermediate in chemical synthesis. It serves as a building block for the preparation of related benzylic derivatives and benzaldehydes, which are employed in dye and pigment manufacture, fragrance and flavor chemistry, and pharmaceutical/agrochemical synthesis. It can be converted to benzyl ethers and benzyl chlorides, enabling its use as a protecting-group reagent and as a reactive intermediate in polymer and coatings formulations. The compound is commonly evaluated for use in cosmetics/personal care as a precursor for fragrance ingredients and specialty actives, depending on formulation requirements and local regulations. It may also function as a reactive intermediate in coatings and inks for binder and resin formulation.
