Used as a corrosion inhibitor in industrial cooling systems due to its ability to form protective films on metal surfaces. Also serves as a precursor in the synthesis of ionic liquids, which are employed as green solvents in catalysis and electrochemical applications. Its long alkyl chain enhances solubility in nonpolar media, making it useful in surface modification and as a surfactant in specialty formulations. Additionally, it finds use in antimicrobial coatings because of its biocidal properties against certain bacteria and fungi.
