Widely used as a phase transfer catalyst in organic synthesis, facilitating the transfer of reactants between immiscible phases, thereby enhancing reaction rates and yields. It is particularly effective in nucleophilic substitution reactions, esterifications, and polymerizations. In the pharmaceutical industry, it aids in the synthesis of complex molecules by improving the solubility of reagents in different solvents. Additionally, it serves as an electrolyte in electrochemical applications, including batteries and sensors, due to its ionic conductivity. In analytical chemistry, it is employed as an ion-pairing agent to improve the separation of compounds in chromatography. Its versatility also extends to the field of material science, where it is used in the preparation of nanoparticles and other advanced materials.
