Used as a phase transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases by transferring reactants across interfaces. Commonly applied in alkylation reactions, polymerizations, and the synthesis of fine chemicals and pharmaceuticals. Its long alkyl chains enhance solubility in nonpolar solvents, making it effective in industrial processes requiring efficient mixing of aqueous and organic components. Also utilized in the formulation of surfactants and as an intermediate in the production of quaternary ammonium compounds for antimicrobial agents and fabric softeners.
