Used extensively as a fluorescent probe in biochemical and cellular studies. It is particularly valuable for labeling biomolecules due to its azide group, which allows for bioorthogonal reactions like click chemistry. This property makes it ideal for tracking and imaging proteins, nucleic acids, and other cellular components in live cells. Additionally, its fluorescence properties enable researchers to monitor enzymatic activities and study molecular interactions in real-time. It is also employed in the development of sensors for detecting specific analytes in biological systems.
