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 neuroactive compounds and antidepressants due to the presence of a primary amine and nitrile group, which can be further functionalized. Commonly employed in asymmetric synthesis routes where the (S)-configuration is essential for biological activity. Also utilized in the preparation of catalysts and ligands for stereoselective reactions in drug manufacturing.
