Widely used as a fluorescent probe in biological and chemical research due to its strong fluorescence properties. It helps in studying enzyme activities, monitoring cellular processes, and detecting metal ions. In the pharmaceutical industry, it serves as a key intermediate in synthesizing various drugs, particularly anticoagulants. Additionally, it is utilized in the development of organic light-emitting diodes (OLEDs) and as a UV absorber in sunscreen formulations. Its applications also extend to analytical chemistry, where it acts as a reference standard for spectrophotometric and chromatographic methods.
