N-Octyl-1,2-ethanediamine is primarily used as a corrosion inhibitor in various industrial applications. It is effective in protecting metal surfaces, particularly in cooling water systems and oil refineries, by forming a protective layer that prevents the interaction of corrosive agents with the metal. Additionally, it is utilized in the formulation of lubricants and fuel additives to enhance performance and extend the lifespan of machinery. In the field of organic synthesis, it serves as a building block for the production of surfactants and emulsifiers, which are essential in the manufacture of detergents, personal care products, and agrochemicals. Its ability to act as a chelating agent also makes it valuable in water treatment processes, where it helps in the removal of heavy metal ions from wastewater.
