Trifluoromethanesulfonic anhydride, oo sidoo kale loo yaqaan triflic anhydride, waa isku dhafka kiimikaad ee leh formula₂O.
Waa aashitada anhydride oo laga soo qaatay triflic acid.
Xaruntani waa koronto-dhal xoogan, faa'iido u leh soo bandhigida kooxda triflyl, CF₃SO₂.
La soo gaabiyo Tf₂O, triflic anhydride waa anhydride aashitada ee triflic acid xoog leh, CF₃SO₂OH.

Trifluoromethanesulfonic Anhydride waa koronto xoog leh oo loo isticmaalo isku dhafka kiimikada si loogu soo bandhigo kooxda triflyl.
Trifluoromethanesulfonic anhydride waxaa loo isticmaalaa in lagu beddelo phenols iyo imine oo loo beddelo triflic ester iyo kooxda NTf. Waa koronto xooggan oo loo isticmaalo hordhaca kooxda triflyl ee isku-dhafka kiimikada. Waxay u adeegtaa sidii reagent ee diyaarinta alkyl iyo vinyl triflates, iyo isku-dhafka stereoselective ee deeq-bixiyeyaasha mannosazide methyl uronate. Waxay u shaqeysaa sidii kicinta glycosylation leh sonkorta anomeric hydroxy si ay u diyaariso polysaccharides.
