Used as a fluorescent probe in analytical chemistry due to its strong emission properties, particularly in detecting nitric oxide in biological systems. Its high sensitivity and selectivity make it valuable in biosensing applications. Also employed in the development of organic semiconductors and optoelectronic materials because of its electron-deficient aromatic structure, which supports charge transport in thin-film devices. Additionally, serves as a building block in synthesizing conjugated polymers for use in solar cells and light-emitting diodes.
