Used as a phase-transfer catalyst in organic synthesis, facilitating reactions between reagents in different phases by improving solubility and reactivity. Commonly employed in nucleophilic substitutions, esterifications, and polymerizations where efficient ion transport is required. Its fluorinated sulfonate group provides enhanced thermal and chemical stability, making it suitable for harsh reaction conditions. Also utilized in electrochemistry as a supporting electrolyte due to its high ionic conductivity and solubility in polar solvents. Additionally, finds use in analytical chemistry for ion-pairing applications and in the preparation of specialty materials such as ionic liquids and functionalized surfaces.
