Used as a chelating agent in metal ion extraction and coordination chemistry due to its multiple carboxylic acid groups and nitrogen heteroatom, enabling stable complex formation with transition metals. Employed in the synthesis of metal-organic frameworks (MOFs) and functional materials. Also serves as a building block in organic synthesis for pharmaceuticals and agrochemicals, where its rigid aromatic structure and functional group arrangement support molecular design. Shows potential in catalysis and sensor development for detecting metal ions in environmental and biological systems.
