Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and central nervous system agents. Its reactive chloromethyl group allows for easy alkylation or attachment to other molecular frameworks, making it valuable in medicinal chemistry for building complex heterocyclic compounds. Commonly employed in the preparation of pyridine-based drug candidates, including those targeting neurological disorders and inflammation. Also utilized in agrochemical research for designing novel pesticides with improved selectivity.
