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 drug molecules. Commonly employed in the preparation of pyridine-based derivatives with potential applications in oncology, inflammation, and central nervous system disorders. Also utilized in agrochemical synthesis for creating novel pesticides and herbicides due to its stable pyridine scaffold and functional versatility.
