Used as a chelating agent in catalytic processes, particularly in transition metal coordination chemistry. Its cyclic structure with multiple nitrogen donors allows selective binding of metal ions, enhancing catalyst stability and reactivity. Commonly applied in oxidation and hydrogenation reactions where controlled metal ion activity is required. Also investigated for use in environmental remediation to capture heavy metals from aqueous solutions due to its selective complexation properties. Shows potential in pharmaceutical formulations as a stabilizer for metal-containing drugs.
