Used primarily as a chelating agent in analytical chemistry, it forms stable complexes with metal ions, particularly iron, enabling the detection and quantification of metals in various samples. It is widely employed in spectrophotometric assays to measure iron concentrations in biological and environmental samples. Additionally, it serves as a reagent in redox titration methods to determine the presence of reducing agents. In research, it is utilized to study enzyme inhibition and metal ion interactions in biochemical systems. Its application extends to material science, where it aids in the synthesis of coordination polymers and metal-organic frameworks.
