Used primarily as a chelating agent in biochemical and analytical applications, it is particularly effective in binding and stabilizing copper ions. This property makes it valuable in spectrophotometric assays for measuring copper concentrations in various samples, including biological fluids and environmental samples. It is also employed in research studies involving redox reactions and electron transfer processes, where precise control of copper ion activity is required. Additionally, it serves as a stabilizer in formulations where copper-catalyzed degradation needs to be minimized. Its water-soluble nature ensures easy integration into aqueous systems, enhancing its utility in laboratory and industrial settings.
