This chemical is widely used as a chelating agent in coordination chemistry due to its ability to form stable complexes with metal ions. It is particularly valuable in the synthesis of metal-organic frameworks (MOFs), where it acts as a linker to create porous structures with applications in gas storage, catalysis, and drug delivery. Additionally, it is employed in the development of luminescent materials and sensors, as its metal complexes often exhibit unique optical properties. In the field of electrochemistry, it serves as a ligand in redox-active complexes for use in energy storage devices and solar cells. Its carboxylic acid groups also make it suitable for surface functionalization and modification in nanotechnology.
