Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It serves as a building block in medicinal chemistry for creating compounds with potential neurological applications, including treatments for cognitive disorders and neurodegenerative diseases. Its iodine functionality allows for further modification through cross-coupling reactions, making it valuable in the design of complex drug molecules. Also employed in research settings to develop new pyridine-based bioactive compounds.
