Primarily used as an intermediate in organic synthesis, it plays a key role in the production of quaternary ammonium compounds, which are widely utilized as surfactants, fabric softeners, and disinfectants. It is also employed in the manufacture of phase transfer catalysts, aiding in reactions between compounds in different phases. Additionally, it serves as a precursor in the synthesis of long-chain alkyl derivatives, which find applications in lubricants, plasticizers, and corrosion inhibitors. Its hydrophobic nature makes it suitable for use in coatings and surface treatments to impart water-repellent properties.
