Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. Its halogen substituents (chloro, iodo, and bromomethyl) allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in Suzuki and Stille coupling reactions to introduce the pyridine core into target molecules. Also utilized in agrochemical research for designing novel bioactive compounds.
