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