Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds targeting central nervous system disorders. Its fluorinated pyrrolidine structure enhances metabolic stability and membrane permeability, making it valuable in medicinal chemistry for optimizing drug candidates. Commonly employed in the preparation of enzyme inhibitors and receptor modulators where stereochemistry and fluorination play critical roles in activity. Also utilized in research settings for structure-activity relationship (SAR) studies due to its chiral center and functional handle for further derivatization.
