Used as a phase-transfer catalyst in organic synthesis, facilitating reactions between reagents in different phases by transferring ions into organic solvents. Enhances the efficiency of oxidation reactions due to the persulfate component, commonly applied in polymerization processes and electrochemical applications. Stable under a range of conditions, making it suitable for use in controlled radical reactions and synthesis of fine chemicals. Also employed in environmental chemistry for degradation of organic pollutants through advanced oxidation processes.
