Used as a fluorescent probe in biochemical and analytical applications due to its naphthalene-based structure, which exhibits strong fluorescence properties. It is employed in studies involving membrane dynamics and protein interactions, where its lipophilic nature allows integration into lipid bilayers. Also utilized in the development of sensors for detecting metal ions or environmental changes in solution, benefiting from changes in emission intensity upon binding events. Its derivatives are explored in medicinal chemistry for designing enzyme inhibitors or receptor ligands.
