Used as a fluorescent labeling agent in biochemical research, particularly for tagging proteins and nucleic acids to study their interactions and localization within cells. It is also employed in the synthesis of organic compounds, where its pyrene moiety provides a useful fluorescent probe for tracking reaction pathways and mechanisms. In material science, it serves as a precursor for developing luminescent materials and polymers with specific optical properties. Additionally, it is utilized in environmental studies to detect and monitor pollutants due to its strong fluorescence and sensitivity to environmental changes.
