Used as a fluorescent probe in biochemical and cellular imaging due to its strong fluorescence properties. It binds selectively to specific biomolecules, enabling visualization of cellular structures and tracking of molecular interactions in live cells. Commonly applied in studies involving protein conformation, nucleic acid dynamics, and membrane behavior. Also utilized in the development of sensors for detecting metal ions or changes in microenvironment polarity. Its high photostability makes it suitable for long-term imaging experiments.
