2,3-Dibromopyridine (CAS# 13534-89-9) horudhac

2,3-dibromopyridine waa unug dabiici ah. Kuwa soo socdaa waa horudhac hantideeda, adeegsigeeda, hababka wax-soo-saarka, iyo macluumaadka badbaadada:
dabeecadda:
-2,3-dibromopyridine waa mid aan midab lahayn ama midab huruud ah oo adag oo leh ur xun.
-Waxay ku milmi kartaa dareerayaasha organic sida ethanol, dimethylformamide, iyo dichloromethane heerkulka qolka, laakiin aan lagu milmin biyaha.
-Dhismahani waa mid u nugul iftiinka iyo hawada, waana in lagu kaydiyaa weel xiran oo ka fog iftiinka.
Ujeedada:
-2,3-dibromopyridine waxaa sida caadiga ah loo isticmaalaa dhexdhexaad muhiim ah oo ku saabsan isku dhafka dabiiciga ah.
-Waxa loo isticmaali karaa beddelka iyo falcelinta uumiga ee isku-dhafka organic.
Habka wax-soo-saarka:
Habka caadiga ah ee diyaarinta 2,3-dibromopyridine waa iyada oo loo marayo falcelinta bromination ee pyridine.
Habka diyaarinta ah ee sida caadiga ah loo isticmaalo waa in lagu kululeeyo pyridine biyaha bromine ee xoogga leh ee falcelinta, iyo natiijada 2,3-dibromopyridine ayaa ka soo kicinaysa xalalka falcelinta ka dib qaboojinta.
Macluumaadka amniga:
-2,3-dibromopyridine waa unug cuncun leh oo keeni kara cuncun isha iyo maqaarka marka la taabto.
-Qalabka ilaalinta ku habboon sida galoofyada, muraayadaha, iyo dharka ilaalinta waa in la xidhaa inta lagu jiro hawlgalka.
- Iska ilaali in aad neefsato boodhkeeda ama gaaskeeda, kana shaqee meel hawo fiican leh.
