Used as an intermediate in the synthesis of organic semiconductors and optoelectronic materials. Its structure supports conjugation and charge transport, making it valuable in the development of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Also employed in the preparation of dyes and fluorescent probes due to its aromatic and electron-donating properties. Serves as a building block in pharmaceutical research, particularly in the design of compounds with biological activity, including potential antitumor and antimicrobial agents. Commonly utilized in cross-coupling reactions to construct complex carbazole-based frameworks for advanced materials.
