Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its reactive chloromethyl group allows for easy alkylation or coupling reactions, making it valuable in constructing complex molecules. Commonly employed in the preparation of drug candidates targeting cancer, inflammation, and central nervous system disorders. Also utilized in agrochemical research for building functionalized pyridine derivatives with potential pesticidal or herbicidal activity.
