Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system drugs. Its stereochemistry makes it valuable for creating enantiomerically pure compounds, improving drug efficacy and reducing side effects. Commonly employed in the production of nootropics and antidepressants due to its ability to influence neurotransmitter activity. Also utilized in the preparation of intermediates for agrochemicals and fine chemicals where optical purity is critical.
