Used as a corrosion inhibitor in industrial systems, particularly in acidic environments where it protects metal surfaces by forming a protective film. Also employed as an intermediate in the synthesis of ionic liquids, which are used in electrochemical applications such as batteries and capacitors. Its long hydrophobic chain enhances surface activity, making it useful in formulations for lubricants and antimicrobial coatings. Additionally, it finds use in research settings for modifying surface properties in sensors and catalytic materials.
