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 medicinal chemistry for creating compounds with potential neurological applications, including treatments for cognitive disorders and neurodegenerative diseases. Its iodinated structure allows for further functionalization through cross-coupling reactions, making it valuable in the design of complex drug molecules. Also employed in research settings for the preparation of pyridine-based ligands and catalysts.
