Widely used as a chelating agent in medical imaging, particularly in the formulation of contrast agents for magnetic resonance imaging (MRI). Its structure allows strong and stable binding to metal ions like gadolinium, enhancing the contrast of MRI scans while minimizing metal ion toxicity. Also employed in radiopharmaceuticals due to its ability to form stable complexes with diagnostic and therapeutic radionuclides. Additionally, it finds use in biochemical research for metal ion stabilization and removal in sensitive assays.
