Application

2,3-Bis(4-bromophenyl)quinoxaline is widely used as a key intermediate in the synthesis of conjugated polymers for organic electronics, particularly in light-emitting diodes (OLEDs) and photovoltaic devices. Its bromine groups facilitate palladium-catalyzed coupling reactions to construct extended π-systems. Researchers also employ it as a scaffold for designing fluorescent probes and bioactive molecules due to its electron-deficient quinoxaline core. In materials science, it serves as a precursor for thermally stable, high-performance polymers.
