Used as a multidentate ligand in coordination chemistry, particularly for stabilizing transition metal and lanthanide ions in catalytic and imaging applications. Its macrocyclic structure enables strong metal ion chelation, making it valuable in the development of MRI contrast agents and luminescent probes. The four benzoic acid arms enhance solubility and allow conjugation to nanoparticles, biomolecules, or solid supports for use in targeted imaging, sensing, and drug delivery systems. Also employed in designing metal-organic frameworks (MOFs) with tailored porosity and functionality for catalysis or environmental remediation.
