Mawu Oyamba
Ndi organic pawiri ndi mankhwala formula C5H3BrFN2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: kristalo wopanda mtundu mpaka wopepuka wachikasu
-Posungunuka: 110-113°C
-Powira: 239°C (kuthamanga kwa mumlengalenga)
-Kuchulukana: 1.92g/cm³
-Kusungunuka: Kusungunuka mu ethanol, dimethylformamide ndi acetonitrile
Gwiritsani ntchito:
-Nthawi zambiri amagwiritsidwa ntchito ngati gawo lapakati pakupanga organic. Itha kugwiritsidwa ntchito popanga mankhwala, mankhwala ophera tizilombo, utoto ndi mitundu ingapo ya mankhwala.
-Pawiriyi imagwira ntchito yofunika kwambiri pazamankhwala, monga kaphatikizidwe ka mankhwala oletsa khansa.
Njira Yokonzekera:
-kapena angapezeke kudzera mndandanda wa organic chemical synthesis reactions. Njira yodziwika yopangira ndi kuteteza, bromination ndi fluorination ya pyrimidines. Njira yeniyeni ya kaphatikizidwe imatha kukonzedwa malinga ndi zosowa zenizeni.
Zambiri Zachitetezo:
-Chidziwitso chachitetezo chapadera chiyenera kutsimikiziridwa molingana ndi miyeso yoyeserera ndikugwiritsa ntchito.
-Pogwiritsa ntchito pawiri, tsatirani mosamalitsa njira zotetezera ma laboratories, kuphatikiza kuvala zida zoyenera zodzitetezera, kupewa kukhudzana ndi khungu ndi maso, kutali ndi moto ndi kutentha.
-Kuwonekera kwanthawi yayitali komanso kutulutsa mpweya wa mankhwalawa kungayambitse ngozi, chifukwa chake muyenera kulabadira njira zodzitetezera ndikuthana nazo motsatira njira yoyenera yoyeserera zinyalala.
