Applications

4-Methylmorpholine N-oxide monohydrate is used as a solvent to prepare cellulose fibers. It is an oxidant and involved in the catalytic OsO<sub>4</sub> oxidation of olefins to cis-1,2-diols. It is also involved in ruthenium catalyzed oxidation of alcohols to aldehydes and ketones.

Notes

Hygroscopic. Store in a cool place. Keep the container tightly closed. Incompatible with strong oxidizing agents.
