Used extensively in coordination chemistry to form stable complexes with metal ions, particularly in the development of contrast agents for magnetic resonance imaging (MRI). Its ability to chelate metal ions like gadolinium makes it valuable in medical diagnostics, enhancing the visibility of internal body structures. Also employed in radiopharmaceuticals for targeted cancer therapy, where it helps deliver radioactive isotopes directly to tumor cells. In research, it serves as a ligand in the study of metal ion behavior and catalysis, aiding in the synthesis of complex molecules. Additionally, it finds use in environmental applications for metal ion sequestration and removal from contaminated water sources.
