Mawu Oyamba
2-Fluoro-3-chloro-5-bromopyridine ndi organic pawiri.
Pawiriyi ndi yolimba yokhala ndi mawonekedwe oyera mpaka achikasu a crystalline. Sipasungunuke m'madzi kutentha kwa firiji, koma imatha kusungunuka muzosungunulira zina monga methanol ndi methylene chloride.
3-Bromo-5-chloro-6-fluoropyridine ili ndi phindu linalake la organic synthesis. Nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati pazochita zosiyanasiyana mu kaphatikizidwe ka organic, monga kaphatikizidwe kazinthu komanso kachitidwe konunkhira ka hydrocarbon. Zochita izi zitha kukhala ndi gawo lofunika kwambiri popanga ma organic molecule.
Njira yokonzekera 3-bromo-5-chloro-6-fluoropyridine ikhoza kuchitidwa kudzera m'njira zosiyanasiyana. Njira yodziwika bwino ndiyo kuchita motsatira njira ya halogenation pogwiritsa ntchito pyridine, choyamba kuyambitsa fluorine pamalo 3, kenako chlorine pamalo 5, kenako bromine pamalo 6.
Zambiri zachitetezo: 3-Bromo-5-chloro-6-fluoropyridine ndi mankhwala ndipo amayenera kusamaliridwa motsatira njira zoyendetsera chitetezo. Zitha kukwiyitsa khungu, maso, ndi kupuma, ndipo zida zoyenera zodzitetezera monga magolovesi, magalasi, ndi zovala zodzitchinjiriza ziyenera kuvalidwa pochita opaleshoni.
Kusungirako ndi kugwiritsira ntchito mankhwala kuyeneranso kuchitidwa motsatira malamulo oyenerera, ndikugawidwa ndi kulembedwa molingana ndi maonekedwe a mankhwalawo. Mukamagwiritsa ntchito, onetsetsani mpweya wabwino komanso kupewa kutulutsa mpweya kapena nthunzi.
