Intangiriro
2-Chloro-3-amino-5-bromopyridine ni ifumbire mvaruganda. Ibikurikira nintangiriro ngufi kumiterere yabyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:
Ubwiza:
- Kugaragara: Ibara ryera ryijimye
- Gukemura: Kubora muri chloroform na Ethanol, gushonga gato mumazi
Koresha:
- Ifumbire irashobora kandi gukoreshwa nkumusemburo wa synthesis organique kandi ikagira uruhare runini muguhuza ibindi bintu kama.
Uburyo:
- Synthesis ya 2-chloro-3-amino-5-bromopyridine isanzwe ikorwa hifashishijwe chlorination-bromination. Itegurwa no gukora 3-amino-4-bromopyridine hamwe na chlorine (nka fosifore trichloride, chloride sulfuryl, nibindi).
Amakuru yumutekano:
- 2-Chloro-3-amino-5-bromopyridine ni imiti kandi isaba ingamba zikwiye nko kwambara uturindantoki twa shimi na masike.
- Mugihe ukoresheje no kubika, guhura na okiside, acide ikomeye, na alkalis ikomeye bigomba kwirindwa kugirango wirinde ingaruka mbi.
- Irashobora kuba imiti ikaze kuruhu, amaso, hamwe nubuhumekero, kandi igomba kwozwa namazi ako kanya nyuma yo guhura nayo kandi hagomba gushakishwa ubuvuzi.
