Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and central nervous system agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating analogs with potential cognitive-enhancing or neuroprotective effects. Also employed in agrochemical research for designing novel pesticides due to its halogenated pyridine core, which can improve bioactivity and metabolic stability. Commonly utilized in cross-coupling reactions to build complex heterocyclic systems in drug discovery programs.
