Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties. Commonly employed in the detection of enzyme activity, particularly in assays involving esterases and proteases, where it acts as a fluorogenic leaving group. Its high quantum yield and photostability make it suitable for imaging in living cells and real-time monitoring of cellular processes. Also utilized in the development of sensors for metal ions and pH due to its responsive fluorescence behavior in different environments. Found in some laser dyes and optoelectronic materials because of its favorable light-emitting characteristics.
