Primarily used as a phase transfer catalyst in organic synthesis, facilitating the transfer of reactants between immiscible phases, enhancing reaction rates and yields. It is particularly effective in nucleophilic substitution reactions and the synthesis of organic compounds. Additionally, it finds application in the preparation of ionic liquids and as an electrolyte additive in electrochemical studies. Its role in polymer chemistry is also notable, aiding in the polymerization processes and stabilization of colloidal systems.
