Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and kinase inhibitors. Its reactive bromomethyl group allows for easy alkylation or coupling reactions, making it valuable in constructing complex drug molecules. Commonly employed in medicinal chemistry for derivatizing pyridine-based structures to enhance biological activity or modify pharmacokinetic properties. Also utilized in the preparation of agrochemicals and functionalized ligands for catalysis.
