Intangiriro
5-Bromo-2,3-diaminopyridine ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:
Ubwiza:
- Kugaragara: 5-Bromo-2,3-diaminopyridine ni umweru kugeza umuhondo woroshye wa kirisiti cyangwa ifu ya kristaline.
- Gukemura: Urusange rushobora gushonga gato mumazi kandi rufite imbaraga zo gukemura neza mumashanyarazi.
Koresha:
- 5-Bromo-2,3-diaminopyridine isanzwe ikoreshwa nka reagent muri reaction ya synthesis.
- Irashobora gukoreshwa nkigihe gito muguhuza ibice cyangwa guhuza ibikorwa.
Uburyo:
Gutegura 5-bromo-2,3-diaminopyridine irashobora kugerwaho nintambwe zikurikira:
1. Banza ushire 2,3-diaminopyridine muri acide hydrochloric aside.
2. Sodium nitrite noneho yongewemo kugirango ibe nitroso.
3. Mugihe cyo kwiyuhagira amazi yubukonje, potasiyumu bromide yongerwaho gukora 5-bromo-2,3-diaminopyridine.
Amakuru yumutekano:
- 5-Bromo-2,3-diaminopyridine ni urugingo ngengabuzima rugomba kubikwa no gukoreshwa neza kugirango wirinde guhura nuruhu n'amaso.
- Iyo ikora, hagomba gufatwa ingamba nziza z'umutekano wa laboratoire, nko kwambara ibikoresho bibarinda (urugero, gants, ibirahure, ikote rya laboratoire, nibindi).
- Koresha uruganda muburyo bwo kwirinda ingaruka zose ziterwa no guhumeka, kuribwa, cyangwa guhura.
Mubushakashatsi bwimiti nubushakashatsi, ni ngombwa gukora akazi keza ko gucunga umutekano wa laboratoire no gukora ukurikije ubuyobozi bwabakozi.
