● Tsananguro: 1, 3-Dimethylurea iParenti inobva uye inoshandiswa seyakawirirana mu orghic synthesis. Iyo isina ruvara crystalline poda nehupfu hushoma. Rinoshandiswawo kuitira Synthesis yeCAfeine, mishonga, machira ezvinyorwa, mishonga uye zvimwe. Muchinyorwa checomputering indasitiri 1,3-dimethurea inoshandiswa seyapakati yekugadzirwa kweFomuldehdehyde-isina kureruka-yekuchengetedza vhiziri yekupedzisa vamiriri. MuSwiss chigadzirwa Nyoresa pane zviuru makumi matatu nezvishanu zvigadzirwa zvine 1,3-dimethylurea, pakati pavo zvinhu gumi neshanu zvakagadzirirwa kushandiswa kwevatengi. Mhando dzechigadzirwa dziri semuenzaniso pendi uye kuchenesa vamiririri. Zviri mukati me1,3-dimethylurea mune zvigadzirwa zvemutengi zviri kusvika gumi muzana (Swiss chigadzirwa Nyoresa, 2003). Shandisa mune cosmetics yakakurudzirwa, asi hapana ruzivo rwuripo sekushandiswa kwayo chaiko mune zvakadai Iyo isina ruvara crystalline yakasimba neyakanyanya solubility mumvura. 1,3-dimethylurea inowanzoshandiswa seyakagadziriswa uye inochera mu organic synthesis. Inogona kushandiswa mune synthesis yemakomisheni akasiyana-siyana senge dhayi, fluorescent dyes, uye mapurasitiki. Muindasitiri yechechi, 1,3-dimethylure inoshandiswawo kujekesa mamwe mishonga yemishonga. Mukuwedzera, inoshandiswa mumaindasitiri akadai sejasi uye majenji. Izvo zvakakosha kuti uzive kuti 1,3-dimethylurea inotsamwisa kune ganda nemaziso, saka nzira dzekuchengetedza dzakakodzera dzinofanira kutorwa kana uchibata.
