Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and agrochemicals. Its functional groups enable selective reactions for constructing complex heterocyclic compounds. Commonly employed in cross-coupling reactions to form carbon-carbon bonds, it plays a role in creating active ingredients in crop protection agents and central nervous system therapeutics. Its aldehyde group allows for further derivatization, making it valuable in medicinal chemistry for lead optimization.
