This chemical is widely used as a chelating agent in coordination chemistry due to its ability to form stable complexes with metal ions, particularly transition metals. It is employed in the development of luminescent materials and sensors, where its metal complexes exhibit strong fluorescence, making it useful in optical and analytical applications. Additionally, it serves as a building block in the synthesis of supramolecular structures and metal-organic frameworks (MOFs), which have applications in gas storage, catalysis, and separation processes. In biochemistry, it is utilized in studying metal ion interactions with biomolecules, aiding in the understanding of enzymatic mechanisms and metal-based drug design. Its derivatives are also explored in dye-sensitized solar cells for improving energy conversion efficiency.
