Used in organic synthesis as a phase-transfer catalyst, facilitating the transfer of reactants between immiscible phases. It is particularly effective in fluorination reactions, where it helps introduce fluorine atoms into organic molecules. Also employed in electrochemical applications, such as electrolytes in batteries, due to its ionic conductivity. Additionally, it serves as a reagent in the preparation of fluorinated compounds, which are valuable in pharmaceuticals and agrochemicals. Its role in stabilizing intermediates in various chemical processes further enhances its utility in industrial and laboratory settings.
