Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners for textiles and paper due to its strong photoluminescent properties. Employed in the development of organic semiconductors and OLED materials, where it contributes to electron transport and light emission in display technologies. Also investigated for its biological activity in medicinal chemistry, particularly as a scaffold in the design of kinase inhibitors and anti-inflammatory agents. Its rigid aromatic structure makes it suitable for use in sensors and molecular probes for detecting metal ions or biomolecules.
