Used as a phase transfer catalyst in organic synthesis, facilitating the movement of reactants between immiscible phases. It is also employed in the preparation of ionic liquids, which are utilized in various industrial processes such as electrochemistry and separation technologies. Additionally, it serves as a stabilizer in the production of polymers and as an additive in the formulation of certain types of adhesives and coatings. In analytical chemistry, it functions as an ion-pairing reagent and mobile phase modifier in high-performance liquid chromatography (HPLC) to enhance the separation and detection of ionic compounds. Its role in enhancing the efficiency of chemical reactions and analyses makes it valuable in research and industrial applications.
