Used as a key intermediate in organic synthesis, particularly in the development of optoelectronic materials. Commonly employed in the production of organic light-emitting diodes (OLEDs) due to its excellent hole-transport properties and thermal stability. Serves as a building block for fluorescent dyes and phosphorescent hosts in display and lighting technologies. Also utilized in the synthesis of high-performance polymers and small molecules for photovoltaic devices. Its bromine functional groups allow for easy modification through cross-coupling reactions, making it valuable in pharmaceutical and agrochemical research.
