Used as a surfactant and corrosion inhibitor in industrial water treatment systems. Its structure allows it to adsorb onto metal surfaces, forming a protective film that reduces corrosion rates in cooling systems and boilers. Also functions as a biocide synergist, enhancing the performance of microbial control agents by disrupting cell membranes in microorganisms. Commonly applied in oilfield chemicals to prevent pipeline corrosion and biofouling. Exhibits good solubility in water and stability over a range of pH conditions, making it suitable for use in closed-loop systems and metalworking fluids.
