Used as a chelating agent, particularly in medical and environmental applications. It effectively binds heavy metal ions such as iron and aluminum, making it valuable in the treatment of metal overload conditions. In pharmaceuticals, it serves as an active ingredient in antidotes for metal poisoning. Also employed in analytical chemistry for selective metal ion detection and removal. Its ability to form stable complexes with transition metals enhances its utility in wastewater treatment and soil remediation. Additionally, it acts as a building block in the synthesis of more complex bioactive molecules.
