Used in organic electronics as a key intermediate for synthesizing hole-transport materials in OLEDs. Serves as a building block for fluorescent dyes and phosphorescent emitters due to its rigid aromatic structure. Employed in the development of photovoltaic materials for organic solar cells. Also utilized in the synthesis of pharmaceuticals and agrochemicals where carbazole derivatives exhibit biological activity. Its bromine functionality allows for easy modification via cross-coupling reactions, making it valuable in material science and medicinal chemistry research.
