Used primarily as a chelating agent in various industrial and laboratory applications, it effectively binds and removes metal ions from solutions. In agriculture, it is employed to treat micronutrient deficiencies in plants by supplying copper in a readily absorbable form. In the medical field, it serves as a component in certain diagnostic tests to stabilize and detect metal ions. Additionally, it is utilized in water treatment processes to control metal contamination and improve water quality. Its ability to form stable complexes with metal ions makes it valuable in analytical chemistry for metal ion quantification and separation.
