Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of selective enzyme inhibitors and receptor modulators. Its fluorinated aromatic structure enhances metabolic stability and membrane permeability, making it valuable in optimizing drug candidates for improved bioavailability. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) targeting central nervous system disorders and inflammatory conditions. The hydrochloride salt form improves solubility and crystallinity, facilitating formulation and purification processes in drug manufacturing.
