Methanesulfonic anhydride yog cov kua qaub anhydride ntawm methanesulfonic acid. Zoo li methanesulfonyl chloride, nws tuaj yeem siv los tsim mesylates (methanesulfonyl esters). Nws muaj nyob rau hauv kev lag luam tab sis kuj tseem tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm phosphorus pentoxide nrog methanesulfonic acid ntawm 80 ° C.

2 P2O5 + 6 CH3SO3H → 3 (CH3SO2)2O + 4 H3PO4
