Used as a fluorescent probe in biochemical and environmental analyses due to its strong emission properties. Its structure allows for sensitive detection of metal ions, particularly aluminum and iron, in aqueous solutions. Also employed in the development of sensors for pH monitoring in biological systems. Acts as a precursor in the synthesis of dyes and optical brighteners for textiles and paper. Shows potential in supramolecular chemistry for constructing host-guest systems because of its hydrogen bonding capability and planar aromatic framework.
