Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties upon binding to specific metal ions or biomolecules. Its structure allows for selective detection of copper and zinc ions in environmental and biological samples. Commonly employed in imaging studies within cellular systems, especially for monitoring intracellular ion fluctuations. Also utilized in the development of chemosensors for real-time detection of reactive oxygen species in living cells. Shows potential in diagnostic tools for neurodegenerative diseases where metal ion imbalance is a marker.
