● 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.
N-methylurea, oo sidoo kale loo yaqaan methylcarbamide ama n-methylcarbamide, waa xarun dabiici ah oo leh qaaciddada kiimikada ee qaaciddada kiimikada ch3nhhconh2. Waa wax laga helo urea, halkaas oo mid ka mid ah atomyada hydrogen-ka ee ku yaal atom nitrogen atom lagu beddelay methyl group.n-methylynea waa mid adag oo adag oo biyo ku dhex jira. Waxaa caadi ahaan loo istcimaalaa sidii dib-u-soo-celinta isku-darka dabiiciga ah, gaar ahaan diyaarinta dawooyinka iyo hawo-mareenka. N-metylylurea waxay ka qeybqaadan kartaa jawaab-celinta kala duwan sida kuwa wax ka qabashada, iyo sifooyin. Waxaa sidoo kale lagugula talinayaa inaad la tashato xaashida xogta badbaadada (SD-yada) si loo maareeyo xeerarka gaarka ah iyo tuurista.
