Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water and boiler systems. It forms a protective film on metal surfaces, preventing oxidation and degradation caused by water and dissolved oxygen. Also employed as an intermediate in the synthesis of quaternary ammonium compounds, which are widely used as biocides and surfactants. Its long hydrocarbon chain provides good solubility in non-polar environments, making it suitable for use in fuel additives and lubricants to improve performance and stability. Additionally, it functions as a flotation agent in mineral processing due to its surface-active properties.
