Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and antidepressants. Its fluorinated aromatic structure enhances metabolic stability and bioavailability in active compounds. Commonly employed in asymmetric synthesis to introduce stereochemistry in drug candidates. Also utilized in the preparation of selective serotonin reuptake inhibitors (SSRIs) and related psychiatric medications due to its structural compatibility with neurotransmitter analogs.
