Used primarily as a fluorescent probe in biochemical and analytical applications due to its strong emission properties upon excitation. Its structure allows for easy derivatization, making it suitable for labeling biomolecules such as proteins and nucleic acids. Commonly employed in imaging techniques to track cellular processes in live-cell microscopy. Also utilized in the development of sensors for detecting metal ions and small molecules in environmental and biological samples. Its stability under physiological conditions enhances its utility in long-term monitoring applications.
