Used as a fluorescent probe in biochemical and analytical applications due to its strong fluorescence under UV light. Commonly employed in enzyme assays, particularly for detecting esterase and glucuronidase activity, where it acts as a substrate that releases a fluorescent product upon enzymatic cleavage. Widely utilized in imaging studies to track cellular processes and monitor drug delivery systems. Also serves as a model compound in photophysical studies and in the development of fluorescent sensors and dyes. Found in some cosmetic formulations as a UV absorber and optical brightener.
