Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) drugs. Its structure allows for selective interaction with neurotransmitter receptors, making it valuable in creating compounds that modulate neurological activity. Commonly employed in the production of antipsychotics and antidepressants due to its ability to enhance metabolic stability and blood-brain barrier penetration in active molecules. Also utilized in research settings for designing novel bioactive compounds with improved pharmacokinetic profiles.
