Used as a fluorescent probe in biochemical and analytical applications due to its strong blue fluorescence under UV light. Commonly employed in enzyme activity assays, particularly for detecting esterase and lipase activity, where it acts as a fluorogenic substrate when linked to specific leaving groups. Also utilized in the development of sensors for metal ions and reactive oxygen species. Its photostability and high quantum yield make it suitable for imaging in biological systems. Additionally, it serves as a model compound in photophysical studies and in the synthesis of more complex fluorescent dyes.
