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 selective cross-coupling reactions, enabling the introduction of various functional groups. Commonly employed in the preparation of biologically active molecules, including antitumor and anti-inflammatory agents. Its bromine moiety facilitates palladium-catalyzed reactions like Suzuki and Heck couplings, making it valuable in drug discovery and development.
