2-bromo-3-methoxypyridine ndi organic pawiri ndi mankhwala chilinganizo C6H6BrNO. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: madzi opanda mtundu
-Kusungunuka: Kusungunuka mu ethanol ya anhydrous ndi zosungunulira za Etere
-Kuwira: 167-169 ° C
-Kuchulukana: 1.568 g/mL
Gwiritsani ntchito:
2-bromo-3-methoxypyridine ili ndi ntchito zina m'munda wa chemistry:
-Monga wapakatikati: angagwiritsidwe ntchito kupanga zinthu zina organic, monga mankhwala, mankhwala ndi utoto.
-Organic synthesis: Itha kutenga nawo gawo pazosiyanasiyana zosiyanasiyana, monga ma electrophilic substitution reaction, ma condensation reaction, etc.
Njira:
2-bromo-3-methoxypyridine kaphatikizidwe njira makamaka zotsatirazi:
1. Ndi zimene 3-methoxypyridine ndi bromine: 3-methoxypyridine anachita ndi bromine ndi mkangano pansi zinthu zamchere kupeza mankhwala 2-bromo-3-methoxypyridine.
2. Pamachitidwe a pyridine ndi 2-Bromo methyl ether: pyridine ndi 2-Bromo methyl ether reaction, pansi pamikhalidwe yoyenera yotenthetsera kapena kugwiritsa ntchito chothandizira kupanga chinthu chomwe mukufuna.
Zambiri Zachitetezo:
Chitetezo cha 2-bromo-3-methoxypyridine chimafunikira chisamaliro. Nawa malangizo ena otetezedwa:
-Pewani kutulutsa mpweya, kukhudza khungu, kapena kulowa m'maso. Valani zida zodzitetezera zoyenera monga magolovesi, magalasi ndi zishango zakumaso mukamagwiritsa ntchito.
-Posunga, iyenera kuyikidwa pamalo abwino mpweya wabwino, kutali ndi moto ndi oxidizing agents.
- Werengani mosamala pepala loyenera lachitetezo musanagwiritse ntchito ndikuligwiritsa ntchito motsatira njira zolondola zogwirira ntchito.
