Description

2,3-Bis(4-bromophenyl)quinoxaline (CAS No. 19802-70-1) is a high-purity brominated quinoxaline derivative with the molecular formula C₂₀H₁₂Br₂N₂. This compound features a quinoxaline core symmetrically substituted with 4-bromophenyl groups at the 2 and 3 positions, making it a valuable building block for organic synthesis and materials science applications. Its rigid aromatic structure and bromine substituents enhance its utility in cross-coupling reactions (e.g., Suzuki, Heck) and as a precursor for luminescent materials or organic semiconductors. Available in >98% purity (HPLC), it is supplied as a crystalline solid with strict quality control to ensure batch-to-batch consistency. Ideal for researchers developing advanced polymers, OLEDs, or pharmaceutical intermediates.

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.
