Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds targeting central nervous system disorders and metabolic diseases. Its fluorinated structure enhances binding selectivity and metabolic stability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid, stereo-defined scaffold. Also utilized in the preparation of protease inhibitors and receptor modulators where fluorine substitution improves pharmacokinetic properties.
