Disclosed are nitrogen-containing heterocyclic compounds of relatively low aquatic toxicity and methods of using the heterocyclic compounds as corrosion inhibitors. The present method is used to inhibit corrosion of a metal surface in contact with an aqueous system using pyrazole derivatives, and provides enhanced protection against corrosion of metals in aqueous systems. The method comprises the use of corrosion inhibitors that are generally resistant to halogen attack and provide good corrosion resistance in the presence of oxidizing halogen-based biocides. Formulations comprising pyrazole derivatives are also disclosed.
