Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its fluorinated aromatic structure makes it valuable in creating compounds with enhanced metabolic stability and binding affinity. Commonly employed in the production of central nervous system (CNS) agents, including antidepressants and antipsychotics, due to its ability to influence neurotransmitter pathways. Also utilized in asymmetric synthesis to introduce chirality in drug candidates during early-stage research and development.
