Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of nicotinic acetylcholine receptor modulators. It serves as a building block for compounds targeting neurological disorders such as Alzheimer's disease, schizophrenia, and nicotine addiction. Its structure allows for functionalization that enhances binding affinity and selectivity in central nervous system drugs. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its rigid, heterocyclic framework.
