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 alkylation, oxidation, and nucleophilic substitution reactions where efficient ion transport enhances yield and reaction rate. Also utilized in electrochemistry as a component in electrode modification and in the preparation of ion-selective membranes. Its long alkyl chains improve solubility in nonpolar media, making it effective in biphasic systems. Additionally, it serves as a surfactant or capping agent in nanomaterial synthesis, controlling the shape and size of nanoparticles such as gold or silver by coating surfaces and preventing aggregation.
