Taw qhia

Ethyl 5-bromo-2-pyrimidincarboxylate yog ib qho organic compound. Cov hauv qab no yog qee cov ntaub ntawv hais txog cov khoom, kev siv, kev npaj thiab kev nyab xeeb ntawm cov compound:

Zoo:

- Cov tsos mob: Ethyl 5-bromo-2-pyrimidincarboxylate yog cov kua tsis muaj xim rau daj ntseg daj.

- Solubility: Nws tuaj yeem yaj hauv cov kuab tshuaj organic xws li ethanol thiab methylene chloride, tab sis nws yog insoluble hauv dej.

Siv:

- Ethyl 5-bromo-2-pyrimidincarboxylic acid feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis.

- Nws kuj tseem tuaj yeem siv los ua kev tshuaj ntsuam reagent hauv thaj chaw tshawb fawb.

Txoj kev:

- Lub synthesis ntawm ethyl 5-bromo-2-pyrimidincarboxylic acid tuaj yeem tau los ntawm esterification ntawm bromobenzoic acid ntawm lub nplhaib pyrimidine.

- Nyob rau hauv cov txheej txheem no, p-bromobenzoic acid thiab isopropyl carbonate yog thawj zaug reacted los tsim isopropyl p-bromobenzoate, thiab tom qab ntawd los ntawm kev ntxiv cov pyrimidine ntau dhau, cua sov rau qhov tsim nyog kub thiab reacting rau ib lub sij hawm, qhov kawg 5-bromo-2- pyrimidincarboxylate ethyl ester tau txais.

- Ua tib zoo saib xyuas qhov kub thiab txias, lub sijhawm tshuaj tiv thaiv, thiab qhov sib piv loj ntawm cov reactants thaum lub sij hawm npaj kom tau txais cov khoom muaj txiaj ntsig zoo thiab purity.

Cov ntaub ntawv kev nyab xeeb:

Ethyl 5-bromo-2-pyrimidincarboxylate yog ib qho organic compound thiab yog flammable.

- Ua raws li kev soj ntsuam kev nyab xeeb niaj hnub thiab hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes thiab tsom iav thaum siv thiab tuav.

- Tsis txhob kov ntawm daim tawv nqaij, qhov muag, thiab nqus pa.

- Thaum muaj kev sib cuag tsis raug, yaug qhov chaw cuam tshuam nrog dej ntau thiab nrhiav kev kho mob.
