Chemische Eigenschaften
white to off-white crystalline solid
Verwenden
N-Methylurea is used as a reagent in the synthesis of bis(aryl)(hydroxyalkyl)(methyl)glycoluril derivatives and is a potential byproduct of caffeine.
Vorbereitung Methode
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.
läuterung methode
Crystallise the urea from EtOH/water, then dry it under vacuum at room temperature. [Beilstein 4 IV 205.]
