Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners for textiles and paper. Exhibits strong UV absorption and fluorescence properties, making it suitable for applications in sensors and luminescent materials. Also investigated for use in organic semiconductors and photovoltaic devices due to its conjugated structure and stability under light exposure. Shows potential in bioimaging probes because of its ability to penetrate cell membranes and emit detectable fluorescence in biological environments.
