Widely used as a phase transfer catalyst in organic synthesis, facilitating the transfer of reactants between immiscible phases, particularly in reactions involving anions. It is employed in the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. Additionally, it serves as a stabilizer in the synthesis of nanoparticles, ensuring controlled size and distribution. In analytical chemistry, it is utilized for ion-pair extraction techniques to enhance the separation and detection of ionic compounds. Its surfactant properties also make it suitable for use in emulsion polymerization processes.
