Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active drugs. Its chiral structure makes it valuable for developing enantiomerically pure compounds, improving drug efficacy and reducing side effects. Commonly employed in asymmetric synthesis routes where the (S)-configuration is critical for biological activity. Also utilized in the development of agrochemicals and specialty chemicals requiring high optical purity.
