Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It plays an important role in the production of certain agrochemicals, including herbicides and insecticides, due to its ability to enhance selectivity and biological activity. Its ethynyl group allows for further functionalization through coupling reactions, making it valuable in medicinal chemistry for building complex molecules. Also employed in research for creating novel pyridine-based compounds with potential neurological applications.
