Used in organic synthesis as a fluorescent protecting group for amines, particularly in the development of peptide-based compounds and bioconjugates. Its strong fluorescence allows for real-time monitoring of reactions and easy detection in complex mixtures without the need for additional staining. Commonly applied in medicinal chemistry for tracking drug delivery systems and in biochemical assays where visualization of molecular interactions is required. Also utilized in the design of sensors and probes due to its environment-sensitive emission properties.
