Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for developing kinase inhibitors and other drug candidates targeting central nervous system disorders and cancer. The tert-butyl protecting group facilitates selective reactions, while the bromo functionality allows for further coupling reactions, such as palladium-catalyzed cross-couplings, enabling rapid diversification in medicinal chemistry campaigns. Its structure supports the development of compounds with improved metabolic stability and binding affinity.
