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

I-Methyl 5-bromo-3-chloro-2-pyridine carboxylate i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:

Umgangatho:
I-Methyl 5-bromo-3-chloro-2-pyridine carboxylate ngulwelo olungenambala okanye oluphuzi. Izinzile kwiqondo lobushushu begumbi, kodwa ukubola kunokwenzeka xa kubonakaliswe kumaqondo obushushu aphezulu, ukukhanya, okanye ii-oxidants ezinamandla.

Sebenzisa:
I-Methyl 5-bromo-3-chloro-2-pyridine carboxylic acid inexabiso elithile lesicelo kwintsimi yeekhemikhali. Isenokusetyenziswa njengesongezo kwi-organic synthesis reagents kunye ne-catalysts.

Indlela:
Indlela yokulungiselela i-methyl 5-bromo-3-chloro-2-pyridine carboxylic acid inokufezekiswa nge-bromination kunye ne-chlorination ye-methyl 2-pyrolinate ester. Ngaphantsi kweemeko ezifanelekileyo, i-methyl 2-picolinate iphendulwa nge-bromine kunye ne-chlorine ukufumana imveliso ekujoliswe kuyo.

Ulwazi ngoKhuseleko: Yikhompawundi evuselelayo enokubangela ukucaphuka kwamehlo, ulusu, kunye nenkqubo yokuphefumla. Kuphephe ukuphefumla iigesi, umphunga, inkungu, okanye uthuli, kwaye kuphephe ukumanzisa ulusu ngexesha lokudibana. Izixhobo ezifanelekileyo zokuzikhusela (PPE), kubandakanywa iiglasi zokukhusela, iiglavu zokukhusela kunye neengubo, kufuneka zigqitywe ngexesha lokuphatha okanye ukuphatha. Ukuba kuyimfuneko, sebenza kwindawo engena umoya kwaye ulandele iinkqubo ezifanelekileyo zokusebenza zokhuseleko. Kufuneka icocwe kakuhle emva konyango ukuthintela ukungcoliseka kwendalo.
