Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties. It is particularly effective in labeling biomolecules such as proteins and nucleic acids for detection in imaging and assay techniques. Its stability under physiological conditions makes it suitable for live-cell imaging. Also employed in the development of sensors for metal ions and small molecules, leveraging changes in fluorescence upon binding events. Additionally, it serves as a building block in the synthesis of more complex fluorophores and optoelectronic materials.
