Taw qhia

3,5-Dibromo-2-methoxypyridine (tseem hu ua 2-bromo-3, 5-dimethoxypyridine) yog cov organic compound. Nws muaj cov qauv molecular ntawm C7H6Br2NO thiab qhov hnyav ntawm 264.94g / mol.3,5-Dibromo-2-methoxypyridine yog cov khoom nrog dawb mus rau daj ntseg daj. Nws tuaj yeem yaj hauv qee cov kuab tshuaj organic hauv chav tsev kub, xws li chloroform, ether thiab methanol.Qhov kev siv lub ntsiab ntawm cov tshuaj no yog ib qho nruab nrab thiab reagent hauv cov organic synthesis. Nws tuaj yeem siv los ua ke ntau yam tshuaj, tshuaj tua kab, dyes thiab lwm yam organic compounds.

Txoj kev tsim cov 3,5-dibromo-2-methoxypyridine feem ntau yog tau los ntawm reacting 3,5-dibromopyridine nrog methanol. Cov tshuaj tiv thaiv tej zaum yuav ua tau nyob rau hauv ib qho chaw inert ntawm qhov kub thiab txias thiab lub sij hawm tshuaj tiv thaiv.

Hais txog cov ntaub ntawv kev nyab xeeb, 3,5-dibromo-2-methoxypyridine yog ib yam khoom muaj phom sij. Nws yuav ua rau khaus thiab corrosion rau tib neeg lub cev, thiab tej zaum yuav ua rau muaj kev puas tsuaj rau ib puag ncig. Thaum siv thiab tuav, yuav tsum tau ntsuas kev nyab xeeb kom tsim nyog, xws li hnav hnab looj tes tiv thaiv, tsom iav thiab khaub ncaws tiv thaiv, ua kom muaj cua zoo, thiab tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Tsis tas li ntawd, cov txheej txheem khaws cia thiab pov tseg kom raug yuav tsum tau ua kom tsis txhob muaj kev sib tsoo thiab kev sib kis. Ua ntej siv, nws yog qhov zoo tshaj rau xa mus rau cov ntaub ntawv kev nyab xeeb ntawm cov tshuaj kom paub meej ntxiv txog kev nyab xeeb.
