Used in organic semiconductor materials due to its electron-rich aromatic structure, enabling applications in OLEDs and organic photovoltaics. Serves as a building block in the synthesis of pharmaceuticals and dyes, particularly in developing compounds with biological activity. Commonly employed in cross-coupling reactions like Suzuki and Buchwald-Hartwig to form C–C and C–N bonds for advanced functional materials. Its halogen positions allow selective functionalization, making it valuable in research and development of electroactive compounds.
