| | Methylurea Usage And Synthesis |
| Chemical Properties | white to off-white crystalline solid | | Uses | N-Methylurea is used as a reagent in the synthesis of bis(aryl)(hydroxyalkyl)(methyl)glycoluril derivatives and is a potential byproduct of caffeine. | | Production Methods | Methylurea is produced on an
industrial scale by passing monomethylamine
into a urea melt. | | Definition | ChEBI: A member of the class of ureas that is urea substituted by a methyl group at one of the nitrogen atoms. | | Purification Methods | Crystallise the urea from EtOH/water, then dry it under vacuum at room temperature. [Beilstein 4 IV 205.] |
