Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) where the fluorine atom enhances metabolic stability and bioavailability. Its bifunctional chloromethyl groups allow for cross-linking in polymer chemistry, making it useful in the production of specialty resins and functionalized materials. Also employed in the preparation of ligands for catalysts in cross-coupling reactions. Due to its reactivity, it serves in the construction of complex organic molecules requiring selective alkylation or ring-functionalization in agrochemicals and electronic materials.
