Used as a chelating agent in analytical chemistry due to its ability to form stable complexes with metal ions. It is particularly effective in the detection and determination of trace metals in environmental and biological samples. Also employed in the synthesis of coordination polymers and metal-organic frameworks (MOFs) for catalytic applications. Shows potential in pharmaceutical research as a building block for compounds with enzyme inhibitory activity. Its derivatives are explored for use in corrosion inhibition and as ligands in homogeneous catalysis.
