Used in organic semiconductor materials due to its electron-transport properties, particularly in OLEDs (organic light-emitting diodes) for display and lighting technologies. Serves as a key intermediate in synthesizing fluorescent dyes and optical brighteners for textiles and paper. Also employed in the development of pharmaceuticals, where its heterocyclic structure contributes to bioactive molecule design, especially in kinase inhibitors and anti-inflammatory agents. Its photostability and emission characteristics make it suitable for use in sensors and fluorescence-based assays.
