Used as a key chiral intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the production of certain antidepressants such as selective serotonin reuptake inhibitors (SSRIs). Its chiral center enables stereoselective synthesis, which enhances the efficacy and safety of the final drug products. Commonly employed in the development of CNS-active compounds, where the resulting fluorinated structures facilitate crossing the blood-brain barrier. Also utilized in the preparation of peptidomimetics and enzyme inhibitors, where fluorinated aromatic moieties improve metabolic stability and binding affinity.
