Used primarily as an intermediate in the synthesis of pharmaceuticals, especially in the development of nicotinic receptor agonists and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in creating pyridine-based drug candidates. Commonly employed in agrochemical research for designing novel pesticides due to its electron-deficient ring system and reactive chloromethyl group. Also utilized in the preparation of ligands for catalysis and in the construction of more complex heterocyclic systems through nucleophilic substitution or cross-coupling reactions.
