Used as a corrosion inhibitor in industrial lubricants and metalworking fluids, particularly in environments exposed to high temperatures and moisture. Its long hydrocarbon chains provide strong surface adsorption on metal substrates, forming a protective film that prevents oxidation and acid attack. Also employed as an intermediate in the synthesis of quaternary ammonium compounds for biocidal applications. In petroleum refining, it acts as an additive to improve the stability and performance of fuels and oils. Additionally, it finds use in flotation agents for mineral processing due to its surfactant properties.
