Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective modifications in drug design, especially in creating analogs with improved metabolic stability. Commonly employed in medicinal chemistry for introducing the tert-butoxycarbonyl (Boc) protecting group while maintaining reactivity through the bromo and fluoro substituents. These functional groups enable further coupling reactions, such as palladium-catalyzed cross-couplings, to build complex aromatic systems found in investigational drugs. Also utilized in the preparation of protease inhibitors and compounds targeting central nervous system disorders.
