Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to construct complex quinoline derivatives. Serves as a building block in the development of bioactive molecules, including antimalarial and anticancer agents. Also utilized in materials science for the synthesis of fluorescent dyes and electron-transport materials in OLEDs. Its bromine functionality allows for easy functionalization, making it valuable in medicinal chemistry research and development.
