Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It serves as a building block in the preparation of biologically active compounds, including those with potential neurological applications. Its aldehyde functionality allows for easy derivatization, enabling the formation of imines, oximes, and other functional groups important in drug design. Also employed in agrochemical research for the development of novel pesticides due to its pyridine-based structure, which can enhance binding affinity and metabolic stability.
