Used as a corrosion inhibitor in industrial water treatment systems, particularly in boiler and cooling water applications. It helps protect metal surfaces by forming a protective film that prevents oxidation and scale buildup. Also functions as an emulsifier and surfactant in oilfield chemicals, enhancing performance in enhanced oil recovery processes. Its morpholine ring structure contributes to thermal stability, making it suitable for high-temperature environments. Additionally, it serves as an intermediate in the synthesis of specialty chemicals, including fabric softeners and antimicrobial agents.
