Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its strong emission properties under UV light. Employed in the development of organic semiconductors for OLEDs and other optoelectronic devices. Acts as a building block in pharmaceuticals, particularly in compounds targeting neurodegenerative diseases and inflammation. Also utilized in sensors for metal ion detection, especially for copper and mercury in environmental monitoring. Its rigid aromatic structure enhances binding selectivity in molecular recognition applications.
