N-Phenylbis(trifluoromethanesulfonamide) (Cat No.: R016820), also known as N-phenylbistriflimide or PhNTf₂, is a strong, non-nucleophilic acid and electrophilic trifluoromethanesulfonylating agent. It features a phenyl group bonded to two trifluoromethanesulfonamide (triflimide) moieties, providing high thermal and chemical stability. Widely used in organic synthesis, it facilitates the formation of triflimide salts and activation of nucleophiles for substitution and coupling reactions. PhNTf₂ is particularly useful in the synthesis of ionic liquids, pharmaceuticals, and advanced materials due to its strong electron-withdrawing properties and good leaving group ability.
