Used primarily as a corrosion inhibitor in industrial water treatment systems, particularly in boiler and cooling water applications. It functions by forming a protective film on metal surfaces, preventing oxidation and degradation caused by water and dissolved oxygen. Its morpholine backbone provides volatility suitable for steam-phase distribution, making it effective in condensate systems to neutralize acidic components and control pH. The dodecyl chain enhances oil solubility and surface activity, improving adsorption onto metal surfaces. Also employed as an intermediate in the synthesis of surfactants and emulsifiers for specialty formulations in oilfield chemicals and metalworking fluids.
