Used as an intermediate in the synthesis of organic semiconductors and optoelectronic materials. Commonly employed in the development of OLEDs (organic light-emitting diodes) due to its ability to form stable, conjugated structures with electron-transport properties. Also utilized in the preparation of dyes, pharmaceuticals, and functional polymers where carbazole derivatives enhance thermal stability and charge transport. Its ketone functionality allows for further chemical modifications, making it valuable in creating complex molecules for advanced material science and medicinal chemistry applications.
