Used as an intermediate in organic synthesis, particularly in the preparation of functional materials for optoelectronic devices. It serves as a building block in the development of organic semiconductors, OLEDs (organic light-emitting diodes), and perovskite solar cells due to its electron-transport properties and structural stability. Its brominated structure allows for further functionalization via cross-coupling reactions, enabling the design of complex conjugated systems. Also employed in the synthesis of pharmaceuticals and dyes where carbazole derivatives are required.
