Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and other bioactive compounds. Its reactive bromomethyl group allows for easy alkylation or substitution reactions, making it valuable in constructing complex heterocyclic systems. Commonly employed in medicinal chemistry for derivatizing pyridine-based structures to enhance binding affinity or modify pharmacokinetic properties. Also utilized in the preparation of kinase inhibitors and central nervous system agents.
