Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and receptor modulators. Its structure supports the design of bioactive molecules due to the presence of fluorine atoms, which enhance metabolic stability and membrane permeability. Commonly employed in medicinal chemistry for optimizing drug candidates targeting neurological disorders, including antidepressants, antipsychotics, and cognitive enhancers. Also utilized in the preparation of enzyme inhibitors and ligands for G-protein coupled receptors (GPCRs). The hydrochloride salt form improves solubility and handling in synthetic processes.
