Daim ntawv thov
Ethyl-5-Bromo-2-carboxylate (CAS: 16732-70-0) yog ib qho tseem ceeb organic chemistry.
Nws cov ntawv thov tseem ceeb suav nrog:
1. Ethyl-5-Bromo-2-carboxylate yog ib qho tseem ceeb bromo-ester disubstituted indole precursor rau kev npaj high-purity indole kws tshuaj intermediates.
2. Ethyl-5-Bromo-2-carboxylate yog dav siv substrate rau hlau-catalyzed coupling cov tshuaj tiv thaiv nyob rau hauv zoo organic synthesis.
3. Ethyl-5-Bromo-2-carboxylate yog cov khoom siv raw rau kev tsim cov nitrogen uas muaj heterocyclic bioactive molecules thiab cov tshuaj ua haujlwm zoo.
Cia
1. Muab kaw kom nruj thiab khaws cia hauv qab 25℃hauv qhov chaw qhuav tsaus kom tsis txhob photodegradation ntawm bromoindole ester qauv.
2. Khaws kom deb ntawm kev cuam tshuam, kev sib txhuam thiab kub siab kom txo tau cov thermal decomposition ntawm bromo thiab ester functional pawg.
3. Ethyl-5-Bromo-2-carboxylate yuav tsum tau muab cais tawm ntawm cov tshuaj tiv thaiv kom muaj zog, muaj zog hauv paus thiab noo noo los tiv thaiv kev debromination thiab ester hydrolysis cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb
1. Tsis txhob nqus cov hmoov av crystalline; hnav plua plav daim npog qhov ncauj thiab tshuaj lom neeg- hnab looj tes tiv thaiv thaum lub sij hawm hnyav thiab hloov.
2. Tsis txhob noj cov khoom; yaug qhov muag thiab daim tawv nqaij uas muaj dej txaus tam sim ntawd tom qab sib cuag.
3. Tshem tawm cov khib nyiab pov tseg thiab lim kom nruj raws li halogenated ester cov txheej txheem tswj cov khib nyiab pov tseg.
Cov txiaj ntsig ntawm Kev Siv
1. Cov pab pawg bromo tuaj yeem sib txuas tau yooj yim thiab derivatized, thaum pab pawg ester txhawb nqa hydrolysis thiab condensation rau ntau hom kev hloov kho indole.
2. Lub nplhaib indole tswj cov qauv ruaj khov nyob rau hauv ib txwm me me synthesis cua sov.
3. Cov khoom purity siab txo qis lwm yam impurities hauv kev lag luam kev lag luam nruab nrab.
