Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and selective receptor modulators. Its fluorinated aromatic structure and amine functionality make it valuable for enhancing metabolic stability and binding affinity in drug candidates. Commonly employed in asymmetric synthesis to introduce stereochemistry in active pharmaceutical ingredients. Also utilized in the preparation of serotonin and dopamine receptor ligands due to its structural similarity to biologically active arylalkylamines.
