Used 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 also employed in spectrophotometric assays to measure iron concentrations in biological and environmental studies. Additionally, it serves as a reagent in the synthesis of coordination compounds and catalysts in organic reactions. Its application extends to corrosion inhibition studies, where it helps evaluate the protective properties of coatings on metal surfaces.
