Taw qhia
Khoom: 5-bromo-2-pyridine carboxylic acid yog xim tsis muaj xim rau lub teeb daj crystalline hmoov. Nws yog soluble hauv dej, cawv thiab ether, thiab me ntsis soluble hauv benzene thiab roj av ether. Nws ruaj khov ntawm chav tsev kub, tab sis yooj yim decomposes ntawm qhov kub thiab txias.
Siv: 5-bromo-2-pyridine carboxylic acid feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis.
Txoj kev npaj: Muaj ntau ntau txoj kev npaj ntawm 5-bromo-2-pyridine carboxylic acid. Ib txoj hauv kev yog los ua 2-pyridine carboxylic acid nrog bromine los tsim 5-bromo-2-pyridine carboxylic acid. Cov tshuaj tiv thaiv no tuaj yeem nqa tawm hauv acetic acid thiab cov tshuaj tiv thaiv kub yog rhuab ntawm chav tsev kub. Thaum kawg ntawm cov tshuaj tiv thaiv, cov khoom tuaj yeem tau txais los ntawm crystallization thiab pom.
Cov ntaub ntawv kev nyab xeeb: 5-Bromo-2-pyridine carboxylic acid feem ntau muaj kev nyab xeeb nyob rau hauv ib txwm siv. Cov txheej txheem kev ua haujlwm nyab xeeb yuav tsum tau ua raws thiab khaws cia rau hauv qhov chaw qhuav, txias, kom deb ntawm qhov hluav taws kub thiab oxidants.
