Beschreibung
Zusammenfassung:	A method of inhibiting corrosion of a metal surface in contact with an aqueous medium is provided. The method may include contacting the metal surface with a corrosion inhibitor composition where the corrosion inhibitor composition may include a compound or salt thereof of formula (I). The disclosed corrosion inhibitor composition is especially useful for inhibiting corrosion in closed loop systems.
