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, DNA interactions, and membrane dynamics. Also utilized in the development of sensors for detecting metal ions in environmental and biological samples. Its high photostability and low toxicity make it suitable for long-term imaging experiments.
