Taw qhia
methyl-2-bromoisonicotinate yog ib qho organic compound nrog cov tshuaj formula C8H6BrNO2. Nws yog xim tsis muaj xim rau lub teeb daj ua kua, volatile ntawm chav tsev kub. Nws yog hygroscopic thiab soluble hauv cov kuab tshuaj organic xws li ethanol thiab dichloromethane.
methyl-2-bromoisonicotinate yog siv los ua catalysts thiab intermediates hauv cov organic synthesis tshuaj. Nws tuaj yeem siv los ua cov khoom siv tseem ceeb hauv kev lag luam tshuaj, tshuaj tua kab thiab dyes.
Txoj kev npaj ntawm methyl-2-bromoisonicotinate feem ntau yog tau los ntawm reacting 2-bromopyridine nrog methyl formate. Cov kev sim tshwj xeeb tej zaum yuav txawv, tab sis feem ntau, cov tshuaj tiv thaiv yog nqa tawm nyob rau hauv alkaline tej yam kev mob, thiab feem ntau siv hauv paus yog sodium hydroxide los yog sodium carbonate.
Rau methyl-2-bromoisonicotinate cov ntaub ntawv kev nyab xeeb, nws yog ib qho ua rau khaus thiab corrosive compound. Kev sib cuag nrog daim tawv nqaij, qhov muag, lossis kab mob ua pa tuaj yeem ua rau khaus thiab tsis xis nyob. Yog li, kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum lub sijhawm ua haujlwm, xws li hnav hnab looj tes tiv thaiv, tsom iav thiab qhov ncauj qhov ntswg. Tsis tas li ntawd, nws yuav tsum tau muab khaws cia rau hauv lub thawv kaw, kom deb ntawm qhov chaw hluav taws kub thiab qhov kub thiab txias. Yog tias muaj xwm txheej tshwm sim, tam sim ntawd yaug qhov chaw cuam tshuam nrog dej ntau thiab nrhiav kev pab kho mob raws sijhawm. Ua raws li cov txheej txheem kev nyab xeeb thiab cov lus pom zoo.
