Used in analytical chemistry as a chelating agent, it effectively binds with metal ions, aiding in the separation and quantification of metals in complex mixtures. It is particularly useful in titrimetric analysis for determining metal concentrations in solutions. Additionally, it finds application in water treatment processes, where it helps in removing heavy metal contaminants by forming stable complexes. In the pharmaceutical industry, it is employed in the synthesis of certain drugs, leveraging its metal-chelating properties to enhance drug stability and efficacy. Its ability to form stable complexes with metals also makes it valuable in industrial processes where metal ion control is critical.
