Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its fluorinated aromatic structure enhances binding affinity and metabolic stability, making it valuable in developing selective serotonin reuptake inhibitors and other neuroactive agents. Also employed in the preparation of chiral building blocks for asymmetric synthesis, where the amine functionality allows for further derivatization. The hydrochloride salt form improves solubility and handling in aqueous reaction systems.
