● 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 N-Methylurea, ka mea i ʻike ʻia ʻo methylcarbamide a i ʻole N-methylcarbamide, he mea hoʻohuihui kūlohelohe me ke ʻano kemika CH3NHCONH2.He mea ia o ka urea, kahi i hoʻololi ʻia ai kekahi o nā ʻātoma hydrogen ma ka atom nitrogen me kahi hui methyl. ʻO N-Methylurea kahi paʻa keʻokeʻo keʻokeʻo e hiki ke hoʻoheheʻe ʻia i ka wai.Hoʻohana maʻamau ia ma ke ʻano he reagent i ka synthesis organik, ʻoi loa i ka hoʻomākaukau ʻana i nā lāʻau lapaʻau a me nā agrochemical.Hiki i ka N-Methylurea ke komo i nā ʻano like ʻole e like me ka amidations, carbamoylations, a me condensations. I ka lawelawe ʻana iā N-Methylurea, he mea nui e hahai i nā hana palekana, me ke komo ʻana i nā mea pale kūpono e like me nā mīkina lima a me nā maka aniani, a me ka hana ʻana ma kahi wahi i hoʻoluʻu maikaʻi ʻia. .He mea maikaʻi nō hoʻi e nīnau i ka pepa ʻikepili palekana (SDS) no nā kuhikuhi kikoʻī o ka lawelawe ʻana a me ka hoʻokuʻu ʻana.
