Used extensively as a fluorescent dye in biological imaging and microscopy due to its strong fluorescence properties. It is particularly valuable in staining cells and tissues for detailed visualization under UV light. Additionally, it serves as a pH-sensitive probe in biochemical research, helping to monitor pH changes in various environments. In material science, it is employed as a fluorescent marker in polymers and coatings to study their properties and behavior. Its photostability and sensitivity make it a preferred choice in analytical chemistry for detecting and quantifying trace substances.
