Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules with potential antihistaminic, anticholinergic, and antipsychotic properties. It is also employed in the preparation of selective receptor modulators due to its ability to cross the blood-brain barrier and interact with neurological targets. Commonly found in research settings for drug discovery, especially in the optimization of cognitive and neurological disorder treatments.
