모노메틸유레아 C화학적 특성, 용도, 생산
화학적 성질
white to off-white crystalline solid
용도
N-Methylurea is used as a reagent in the synthesis of bis(aryl)(hydroxyalkyl)(methyl)glycoluril derivatives and is a potential byproduct of caffeine.
생산 방법
Methylurea is produced on an
industrial scale by passing monomethylamine
into a urea melt.
정의
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.]
