Used primarily as a chelating agent in coordination chemistry, it forms stable complexes with various metal ions, making it valuable in the study of metal-ligand interactions. Its ability to bind metals is exploited in catalysis, where it enhances the efficiency of certain chemical reactions. Additionally, it is employed in the development of sensors and molecular devices due to its unique binding properties. In analytical chemistry, it aids in the separation and detection of specific metal ions in complex mixtures. Its sulfur and nitrogen donor atoms make it suitable for applications in bioinorganic chemistry, where it mimics biological ligands in metal-containing enzymes.
