Used as a highly effective reagent in organic synthesis, particularly for introducing the triflimide group into molecules. It plays a key role in the preparation of triflimide salts, which are strong, thermally stable acids used as catalysts in various reactions. Commonly employed in the synthesis of pharmaceuticals and agrochemicals due to its ability to enhance reaction efficiency and selectivity. Also utilized in materials science for modifying electronic properties of compounds, especially in the development of ionic liquids and electrolytes for advanced battery systems. Its high leaving group ability makes it valuable in cross-coupling reactions and transition-metal-catalyzed transformations.
