Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its strong electron-donating amine groups and rigid conjugated structure. Its derivatives are employed in organic light-emitting diodes (OLEDs) as blue or green emitters. Also investigated for use in bioimaging probes because of its ability to cross cell membranes and exhibit low cytotoxicity while maintaining high fluorescence quantum yield. Additionally, it serves as a building block in the development of kinase inhibitors and other pharmaceuticals targeting neurodegenerative diseases.
