Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active agents. Its enantiomeric purity makes it valuable for developing drugs with improved efficacy and reduced side effects. Commonly employed in asymmetric synthesis to introduce chiral centers in bioactive molecules. Also utilized in the preparation of fluorinated analogs of aromatic amines for medicinal chemistry research.
