Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules. Its reactive chloromethyl group allows for easy alkylation or substitution, making it valuable in constructing heterocyclic compounds. Commonly employed in medicinal chemistry for creating analogs with potential antimicrobial, antiviral, or anti-inflammatory properties. Also utilized in the preparation of covalent inhibitors where selective binding to target proteins is required.
