● Amakilasi amakhemikhali: ama-nitrogen compounds -> amakhompiyutha e-Urea
● Ukumamatheka kwe-canonical: cnc (= o) nc
● Ingozi yokuphefumula: Akukho okukhonjiswayo kunganikezwa ngesilinganiso lapho kufinyelelwa khona kwale nto ngengozi.
● Imiphumela yokuvezwa kwesikhathi esifushane: Into imnandi kakhulu emehlweni nasesikhumba.
● Ukuchazwa: 1, 3-DimethLulure kuyinto esuselwa e-urea futhi esetshenziswa njengomphakathi ekuhlolweni kwe-organic. Kuyimpuphu ye-crystalline engenamibala enobuthi obuncane. Iphinde isetshenziselwe ukuhlanganiswa kwe-caffeine, ama-Pharmachemicals, izinsiza zezindwangu, ama-herbicides nokunye. Embonini yokusebenza kwendwangu engu-1,3-dimethylurea isetshenziswa njengoMphakathi ukukhiqizwa kwama-ejenti wokuqeda ukunakekelwa okulula kwezindwangu. Ebhalisweni lomkhiqizo waseSwitzerland Kunemikhiqizo engama-38 equkethe i-1,3-dimethylurea, phakathi kwazo eziyi-17 zemikhiqizo enzelwe ukusetshenziswa kwabathengi. Izinhlobo Zomkhiqizo ziwukufunda kanye nama-ejenti wokuhlanza. Okuqukethwe okungu-1,3-dimethylurea kwimikhiqizo yabathengi kufinyelela ku-10% (Rejista Yomkhiqizo waseSwitzerland, 2003). Ukusetshenziswa kwezimonyo kuhlongoziwe, kepha akukho lwazi olutholakala ngokusetshenziswa kwangempela kwalezo zinhlelo zokusebenza ezinjalo Kuyi-crystalline engenamibala eqinile ene-soubity ephezulu emanzini. I-1,3-timethylurea ivame ukusetshenziswa njenge-solvent kanye ne-catalyst ku-organic synthesis. Ingasetshenziswa ekuhlanganiseni kwamakhompiyutha ahlukahlukene anjengedayi, amadasi e-fluorescent, namapulasitiki. Embonini yezemithi, i-1,3-dimethylurea nayo isetshenziselwa ukuhlanganisa abanye abaphakathi kwemithi. Ngaphezu kwalokho, isetshenziswa ezimbonini ezinjengezimbobo kanye nama-adhesives. Kubalulekile ukuqaphela ukuthi i-1,3-dimethylurea iyacasula esikhunjeni namehlo, ngakho-ke kufanele kuthathwe izinyathelo zokuphepha okufanele lapho ziphathwa.
● Ukusetshenziswa Ngokuhambisana ne-β-cyclodextrin derivatives, ukwakha ama-mixtures aphansi ancibilikise (LMMS), angasetshenziswa njengama-solves we-hydroformylition kanye ne-tsuji-trost actices.to-aryl-3,4-dihydropymididinones nge-biginelli condensation ngaphansi kwezimo ze-solvent ngaphansi kwezimo ezingenayo.
