Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of CNS-targeted drugs. Its fluorinated pyrrolidine core enhances blood-brain barrier permeability, making it valuable in neurology and psychiatry drug design. The hydroxyl and benzyl groups allow further functionalization, enabling tailored modifications for structure-activity relationship studies. Also explored in medicinal chemistry for optimizing metabolic stability and binding affinity in receptor ligands.
