Widely used as a chelating agent in medical imaging, particularly in MRI contrast agents. Its structure allows strong and stable binding to metal ions like gadolinium, enhancing image clarity and diagnostic accuracy. Due to its high selectivity and low toxicity, it improves the safety profile of contrast agents by minimizing the release of free metal ions in the body. Also employed in radiopharmaceuticals for targeted imaging and therapy, where precise metal ion coordination is essential. Its solubility and stability in physiological conditions make it suitable for in vivo applications.
