Used as a chemosensor for detecting metal ions, particularly mercury (Hg²⁺) and copper (Cu²⁺), due to its ability to undergo color changes upon binding with these ions. Exhibits high selectivity and sensitivity in both solution and test strip formats, making it suitable for environmental monitoring and analytical applications. Also investigated for its potential in supramolecular chemistry and as a building block in the synthesis of biologically active compounds. Shows promise in fluorescence-based assays and molecular recognition studies.
