Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties upon binding to specific biomolecules. Its structure allows for high sensitivity in detecting metal ions, particularly zinc and copper, in biological systems. Commonly applied in cellular imaging to monitor intracellular ion concentrations and enzyme activity. Also utilized in the development of sensors for environmental monitoring, where it helps detect trace metal contaminants in water and biological samples. Shows potential in pharmaceutical research for tracking drug delivery and studying protein interactions.
