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

I-Methyl 5-bromo-3-chloro-2-pyridine carboxylate iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

Ikhwalithi:
I-Methyl 5-bromo-3-chloro-2-pyridine carboxylate iwuketshezi olungenambala noma oluphuzi. Iqinile uma kuqhathaniswa nezinga lokushisa legumbi, kodwa ukubola kungase kwenzeke lapho kubhekene nezinga lokushisa eliphezulu, ukukhanya, noma ama-oxidants aqinile.

Sebenzisa:
I-Methyl 5-bromo-3-chloro-2-pyridine carboxylic acid inenani elithile lesicelo endaweni yamakhemikhali. Ingasetshenziswa futhi njengesengezo kuma-organic synthesis reagents nama-catalysts.

Indlela:
Indlela yokulungiselela i-methyl 5-bromo-3-chloro-2-pyridine carboxylic acid ingafinyelelwa ngokugcotshwa nokucwiliswa kwe-methyl 2-pyrolinate ester. Ngaphansi kwezimo ezifanele, i-methyl 2-picolinate isabela nge-bromine ne-chlorine ukuze kutholwe umkhiqizo okuhlosiwe.

Ulwazi Lokuphepha: Kuyinhlanganisela evuselelayo engabangela ukucasuka kwamehlo, isikhumba, kanye nesistimu yokuphefumula. Gwema ukuhogela amagesi, umhwamuko, inkungu, noma uthuli, futhi ugweme ukumanzisa isikhumba ngesikhathi sokuxhumana. Izinto zokuzivikela ezifanelekile (i-PPE), okuhlanganisa izibuko zokuphepha, amagilavu ​​okuzivikela kanye nezingubo zokugqoka, kufanele zigqokwe ngesikhathi sokuphatha noma sokuphatha. Uma kunesidingo, sebenza endaweni enomoya omuhle futhi ulandele izinqubo ezifanele zokusebenza zokuphepha. Kufanele ihlanzwe kahle ngemva kokwelashwa ukuze kugwenywe ukungcoliswa kwemvelo.
