Used as a phase-transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases by enhancing ion mobility. Particularly effective in alkylation, esterification, and nucleophilic substitution reactions due to its thermal stability and solubility in both aqueous and organic media. Also employed in electrochemical applications as an electrolyte component, where its fluorinated anion contributes to improved conductivity and stability. Additionally, serves as a reagent in the preparation of other ammonium salts and ionic liquids for specialized industrial processes.
