Used as a reagent in analytical chemistry for the detection and quantification of metal ions, particularly copper and nickel, due to its strong chelating properties. It plays a role in solvent extraction processes for separating and recovering metals from ores or waste materials. In research, it serves as a ligand in coordination chemistry to study the behavior of metal complexes. Additionally, it has applications in the synthesis of organic compounds and as an intermediate in the production of specialized chemicals. Its selective binding ability makes it valuable in environmental monitoring for metal contamination analysis.
