Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of central nervous system agents and antidepressants. Its enantiomerically pure structure makes it valuable for developing active pharmaceutical ingredients where stereochemistry impacts drug efficacy and safety. Commonly employed in asymmetric synthesis and catalysis to introduce stereocenters in complex molecules. Also utilized in the preparation of peptidomimetics and other bioactive compounds due to its amino ester functionality and aromatic substitution pattern.
