N-Methylmorpholine-N-oxide or NMO is an organic compound. This heterocyclic amine oxide and morpholine derivative is used in organic chemistry as a co-oxidant and sacrificial catalyst in oxidation reactions for instance in osmium tetroxide oxidations and the Sharpless asymmetric dihydroxylation or oxidations with TPAP. NMO is commercially supplied both as a monohydrate C₅H₁₁NO₂.H₂O and as the anhydrous compound. NMO is used as a solvent for Lyocell manufacturing.
