Used as a fluorescent probe in biological imaging due to its strong emission properties and selectivity toward specific cellular components. Exhibits high sensitivity in detecting metal ions, particularly aluminum and zinc, in environmental and physiological samples. Applied in the development of chemosensors for real-time monitoring of reactive oxygen species in living cells. Also investigated for its potential as a photosensitizer in photodynamic therapy, showing promising results in targeted cancer cell destruction under light irradiation. Its coumarin-based structure enhances membrane permeability, making it suitable for intracellular applications.
