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, oxidations, and polymerizations where it enhances reaction rates and yields. Also employed in the preparation of nanomaterials and as a surfactant in emulsion systems due to its long hydrophobic chains. Its high solubility in nonpolar solvents makes it suitable for interfacial reactions and extraction processes.
