Used primarily as a fluorescent probe in biochemical and analytical applications due to its strong emission properties when bound to specific proteins or enzymes. Its rigid polycyclic structure enhances stability and quantum yield, making it suitable for imaging cellular processes and monitoring conformational changes in biomolecules. Also employed in the development of sensors for detecting metal ions and small organic molecules in environmental and clinical samples. The compound’s amide and heterocyclic groups allow for selective interactions in receptor-ligand studies, supporting its use in drug discovery as a labeling agent for high-throughput screening.
