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 agrochemicals for creating novel pesticides due to its reactive ethynyl and chloro functional groups that allow for further chemical modifications. Its structure enables coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Also employed in research for developing new bioactive molecules and functional materials.
