5-Bromo-3-chloro-2-pyridinecarboxylic acid methyl ester (CAS# 1214336-41-0)

Methyl 5-bromo-3-chloro-2-pyridine carboxylate ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:

Ubwino:
Methyl 5-bromo-3-chloro-2-pyridine carboxylate ndi madzi opanda mtundu kapena achikasu. Imakhala yosasunthika potentha, koma imatha kuwola ikakumana ndi kutentha kwambiri, kuwala, kapena ma okosijeni amphamvu.

Gwiritsani ntchito:
Methyl 5-bromo-3-chloro-2-pyridine carboxylic acid ili ndi phindu linalake pamankhwala. Itha kugwiritsidwanso ntchito ngati chowonjezera mu organic synthesis reagents ndi catalysts.

Njira:
Kukonzekera njira ya methyl 5-bromo-3-chloro-2-pyridine carboxylic asidi chingapezeke mwa bromination ndi chlorination wa methyl 2-pyrolinate ester. Pansi pamikhalidwe yoyenera, methyl 2-picolinate imayendetsedwa ndi bromine ndi chlorine kuti ipeze zomwe mukufuna.

Chidziwitso cha Chitetezo: Ndi chinthu cholimbikitsa chomwe chingayambitse kuyabwa m'maso, khungu, ndi kupuma. Pewani kutulutsa mpweya, nthunzi, nkhungu, kapena fumbi, ndipo pewani kunyowetsa khungu mukakumana. Zida zodzitetezera zoyenerera (PPE), kuphatikiza magalasi otetezera, magolovesi oteteza ndi mikanjo, ziyenera kuvalidwa pogwira kapena pogwira. Ngati ndi kotheka, gwirani ntchito pamalo olowera mpweya wabwino ndikutsata njira zoyendetsera chitetezo. Iyenera kutsukidwa bwino pambuyo pa chithandizo kuti tipewe kuipitsa chilengedwe.
