Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) disorders. Its enantiomeric purity makes it valuable in producing drugs with higher selectivity and reduced side effects. Commonly employed in the preparation of serotonin and dopamine receptor modulators. Also utilized in the manufacture of fluorinated analogs of bioactive molecules to enhance metabolic stability and bioavailability. Widely applied in research and development within medicinal chemistry for structure-activity relationship (SAR) studies.
