Used in the synthesis of pharmaceutical intermediates, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its chiral structure makes it valuable in asymmetric synthesis for developing enantiomerically pure drugs. Commonly employed in research and development of treatments for neurological and psychiatric disorders such as depression and anxiety. Also utilized in the preparation of bioactive molecules where stereochemistry plays a critical role in biological activity.
