Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to undergo cross-coupling reactions, enabling the formation of complex heterocyclic systems. Commonly employed in the preparation of biologically active molecules targeting tyrosine kinases and other enzyme families involved in signal transduction pathways. Its bromine functionality allows for selective functionalization via palladium-catalyzed reactions, making it valuable in structure-activity relationship (SAR) studies during drug discovery.
