Used primarily in pharmaceutical synthesis as a chiral building block for the development of active pharmaceutical ingredients (APIs). Its stereochemistry makes it valuable in creating enantioselective drugs, particularly in central nervous system agents and cardiovascular medications. Commonly employed in the preparation of nootropic and neuroprotective compounds due to the pyrrolidinyl and aniline functional groups enhancing blood-brain barrier penetration. Also utilized as a resolving agent in asymmetric synthesis and in the production of specialty intermediates for medicinal chemistry research.
