● Hoʻohana: Hoʻohana ʻia ʻo N-Methylurea ma ke ʻano he reagent i ka synthesis o bis(aryl)(hydroxyalkyl)(methyl)glycoluril derivatives a he mea hiki ke hoʻohana i ka caffeine.
ʻO ka Methylurea, ka mea i kapa ʻia ʻo N-methylurea, he pūhui kemika me ke ʻano mole mole CH4N2O.He mea hoʻohuihui ia no ka papa o ka urea derivatives.Loaʻa ka Methylurea mai ka urea ma o ka hoʻololi ʻana i kekahi o nā mana hydrogen me kahi hui methyl (-CH3).Hiki iā ia ke lilo i kumu o ka hui kalapona (-C=O) a i ʻole ka hui amino (-NH2) i nā ʻano hoʻololi synthetic.Hoʻohana pū ʻia ka Methylurea i ka hana ʻana i nā lāʻau lapaʻau, agrochemical, a me nā mea pena.
