This chemical is widely used as a phase-transfer catalyst in organic synthesis, facilitating the transfer of reactants between immiscible phases, such as aqueous and organic layers. It is particularly effective in reactions like nucleophilic substitutions, oxidations, and polymerizations, enhancing reaction rates and yields. Additionally, it serves as an electrolyte additive in electrochemical applications, improving the stability and performance of batteries and supercapacitors. Its role in stabilizing ionic species also makes it valuable in the preparation of ionic liquids and in the study of ion transport mechanisms.
