Used in organic synthesis as an intermediate for pharmaceuticals and functional materials, particularly in the development of optoelectronic compounds. Serves as a building block in the preparation of carbazole-based derivatives for applications in organic light-emitting diodes (OLEDs) and photovoltaic cells. The bromine functionality allows for further modification via cross-coupling reactions, enabling the construction of complex aromatic systems. Also employed in the synthesis of bioactive molecules and drug candidates where carbazole scaffolds exhibit antitumor, antimicrobial, or anti-inflammatory properties.
