Used as a corrosion inhibitor in water treatment systems, particularly in cooling towers and boilers. It helps protect metal surfaces by forming a protective film that prevents oxidation and scale buildup. Also employed in gas treating processes to reduce degradation of equipment exposed to acidic gases like CO₂ and H₂S. Its hydrophilic nature enhances solubility in aqueous systems, improving performance in low-foaming formulations. Additionally, it acts as an intermediate in the synthesis of specialty surfactants and emulsifiers for industrial cleaning products.
