Mawu Oyamba
Katundu: 5-bromo-2-pyridine carboxylic acid ndi wopanda mtundu mpaka kuwala wachikasu crystalline ufa. Amasungunuka m'madzi, mowa ndi ether, ndipo amasungunuka pang'ono mu benzene ndi petroleum ether. Ndiwokhazikika kutentha, koma amawola mosavuta pa kutentha kwakukulu.
Ntchito: 5-bromo-2-pyridine carboxylic asidi nthawi zambiri ntchito ngati wapakatikati mu kaphatikizidwe organic.
Kukonzekera njira: Pali njira zokonzekera za 5-bromo-2-pyridine carboxylic acid. Njira yodziwika bwino ndikuchita 2-pyridine carboxylic acid ndi bromine kupanga 5-bromo-2-pyridine carboxylic acid. Izi zitha kuchitika mu acetic acid ndi kutentha komwe kumatenthedwa firiji. Pamapeto pa zomwe zimachitika, mankhwalawa amatha kupezeka ndi crystallization ndi kusefera.
Zambiri Zachitetezo: 5-Bromo-2-pyridine carboxylic acid nthawi zambiri imakhala yotetezeka pakagwiritsidwe ntchito bwino. Njira zotetezera ziyenera kutsatiridwa ndikusungidwa pamalo owuma, ozizira, kutali ndi kuyatsa ndi okosijeni.
