Used as a key chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its fluorinated aromatic structure enhances binding selectivity and metabolic stability, making it valuable in the development of enzyme inhibitors and receptor modulators. Commonly employed in the production of anticonvulsant and antiparkinsonian drugs due to its ability to mimic natural amino acids while resisting degradation. Also utilized in peptidomimetic research to design stable, high-affinity ligands for neurotransmitter receptors.
