3-Bromo-5-chloropicolinic acid ndi organic pawiri.
Ubwino:
3-Bromo-5-chloro-2-pyridine carboxylic acid ndi kristalo wopanda mtundu wokhala ndi mawonekedwe apadera komanso mawonekedwe a thupi. Ndiwolimba kutentha kutentha ndipo amasungunuka muzitsulo zina za organic, monga methanol, dimethylformamide, ndi zina zotero. Pawiriyi imakhala yosasunthika mumlengalenga ndipo imatha kukhudzidwa ndi zinthu zina za mankhwala.
Mapulogalamu: Kapangidwe kake kake kapadera ka mankhwala kumapangitsa kuti ikhale ndi mphamvu zambiri zogwiritsira ntchito.
Njira:
Njira wamba yokonza 3-bromo-5-chloro-2-pyridine carboxylic acid imapezeka ndi kaphatikizidwe kamankhwala. Mwachindunji, ikhoza kuyamba kuchokera ku 2-pyrolinic acid kapena 2-pyridone, ndipo pambuyo pa zochitika zingapo, maatomu a bromine ndi klorini amatha kuyambitsidwa kuti potsirizira pake apange pawiri.
Zambiri Zachitetezo:
Mukamagwiritsa ntchito 3-bromo-5-chloro-2-pyridine carboxylic acid, njira zoyendetsera chitetezo ziyenera kutsatiridwa. Ichi ndi mankhwala komanso fumbi kapena njira yomwe iyenera kupewedwa pokoka mpweya. Zida zodzitetezera zoyenerera monga zovala zodzitetezera m'maso, magolovesi ndi zovala zodzitetezera ziyenera kuvalidwa pogwira ntchito. Chigawocho chimasungidwa ndikutayidwa motsatira malamulo oyenera ndipo zinyalala zimatayidwa bwino.
