Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its structure supports the development of central nervous system agents, including antidepressants and anxiolytics, due to its affinity for monoaminergic receptors. Commonly employed in asymmetric synthesis to introduce chirality in drug molecules. Also utilized in the preparation of radiolabeled compounds for receptor binding studies and PET imaging.
