Used as a phase-transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases by enhancing reactivity and selectivity. Commonly applied in alkylation, esterification, and oxidation processes. Also serves as a mild ammonium source in the preparation of functional materials and fine chemicals. Its low volatility and thermal stability make it suitable for use in solvent-free or green chemistry applications. Additionally, employed in electrochemical processes and as a buffering agent in certain industrial formulations.
