I-5-bromo-2-pyridinecarboxylic acid ethyl ester (CAS# 77199-09-8)
Intshayelelo
I-Ethyl 5-bromo-2-pyrimidincarboxylate i-organic compound. Olu lulandelayo lulunye ulwazi malunga neepropati, ukusetyenziswa, iindlela zokulungiselela kunye nokhuseleko lwekhompawundi:
Umgangatho:
- Imbonakalo: Ethyl 5-bromo-2-pyrimidincarboxylate ngulwelo olungenambala ukuya kumthubi.
- Ukunyibilika: Inokunyibilika kwi-solvents ye-organic efana ne-ethanol kunye ne-methylene chloride, kodwa ayinakunyibilika emanzini.
Sebenzisa:
- I-Ethyl 5-bromo-2-pyrimidincarboxylic acid idla ngokusetyenziswa njengento ebalulekileyo ephakathi kwi-organic synthesis.
- Inokusetyenziswa kwakhona njenge-reagent yokuhlalutya kwiindawo zophando.
Indlela:
- I-synthesis ye-ethyl 5-bromo-2-pyrimidincarboxylic acid inokufumaneka nge-esterification ye-bromobenzoic acid kwindandatho ye-pyrimidine.
- Kule nkqubo, i-p-bromobenzoic acid kunye ne-isopropyl carbonate iqala ukusabela ukuvelisa isopropyl p-bromobenzoate, kwaye ngoko yongeza i-pyrimidine engaphezulu, ukufudumeza kwiqondo lokushisa elifanelekileyo kunye nokuphendula ixesha elithile, i-5-bromo-2-yokugqibela I-pyrimidincarboxylate ethyl ester ifunyenwe.
- Nika ingqalelo kwiqondo lobushushu lokusabela, ixesha lokuphendula, kunye nomlinganiselo wobunzima bereactants ngexesha lokulungiselela ukufumana imveliso enesivuno esikhulu kunye nobunyulu.
Ulwazi ngoKhuseleko:
- I-Ethyl 5-bromo-2-pyrimidincarboxylate i-organic compound kwaye inokutsha.
- Landela iinkqubo zokhuseleko lwaselabhoratri kwaye unxibe izixhobo ezifanelekileyo zokhuseleko ezifana neeglavu kunye nezibuko xa usebenzisa naxa uphethe.
• Kuphephe ukudibana nolusu, amehlo, kunye nokuphefumla.
- Kwimeko yokudibanisa ngengozi, hlambulula indawo echaphazelekayo ngamanzi amaninzi kwaye ufune unyango.
