N-MethylureA, tseem hu ua methylcarbamide lossis n-methylcarbamide, yog cov organic sib xyaw nrog cov tshuaj siv tshuaj ch3nhconh2. Nws yog ib qho kev ua kom zoo ntawm urea, qhov twg ib ntawm hydrogen atoms ntawm cov nitrogen atom yog hloov nrog lub methyl pawg.n-MetylureAst yog ib tug dawb crystalline khoom uas yog soluble hauv dej. Nws yog ib qho uas siv tau ua lub reagent hauv cov khoom siv hauv siab organic, tshwj xeeb hauv kev npaj ntawm cov tshuaj thiab agnaphicals. N-MetylureAce tuaj yeem koom nrog ntau yam kev tawm tsam xws li hnab looj tes tsim nyog xws li hnab looj tes tsim nyog xws li hnab looj tes tsim nyog xws li hnab looj tes tsim nyog xws li hnab looj tes tsim nyog Nws yog qhov kev nyab xeeb los sab laj cov ntaub ntawv nyab xeeb (SDS) rau kev tuav thiab pov tseg tshwj xeeb.
