Used as a phase-transfer catalyst in organic synthesis, facilitating reactions between reagents in different phases by transferring ions into organic solvents. Commonly applied in nucleophilic substitutions, esterifications, and polymerizations where mild basic conditions are needed. Also employed in electrochemistry as a supporting electrolyte due to its good solubility and stability in aprotic solvents. Its trifluoroacetate anion offers enhanced leaving group ability, useful in deprotection steps and fluorination reactions.
