Used as a catalyst in oxidation reactions, particularly in the aerobic oxidation of hydrocarbons and alcohols. It enhances reaction efficiency when combined with transition metal catalysts, enabling milder reaction conditions and improved selectivity. Commonly applied in organic synthesis for producing carbonyl compounds such as aldehydes, ketones, and carboxylic acids. Also employed in fuel cell research and environmental applications where selective oxidation is required. Its ability to generate active oxygen species makes it valuable in radical-mediated transformations.
