Mawu Oyamba
5-Bromo-3-fluoropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- 5-Bromo-3-fluoropyridine ndi yolimba ndi morphology ya makhiristo oyera kapena achikasu.
- Ndi gulu la organohalogen lomwe lili ndi zochita zambiri zamankhwala.
- 5-Bromo-3-fluoropyridine ndi osasungunuka m'madzi kutentha firiji, koma sungunuka mu zosungunulira organic monga ethanol ndi ethers.
Gwiritsani ntchito:
- 5-Bromo-3-fluoropyridine nthawi zambiri amagwiritsidwa ntchito ngati reagent yofunika mu kaphatikizidwe ka organic.
- Ili ndi ma electrophilic amphamvu m'malo ndi kuyambitsa, ndipo imatha kugwiritsidwa ntchito m'malo, kuphatikiza ndi ma cyclization pamachitidwe a organic synthesis.
Njira:
- 5-Bromo-3-fluoropyridine ikhoza kupangidwa ndi njira zosiyanasiyana, njira yodziwika kwambiri ndikuchita bromofluoropyridine ndi acetonitrile.
- 3-Bromopyridine ingathenso kupezedwa ndikuyamba kuchitapo kanthu ndi lithiamu subbromide kupanga 3-bromopyridine, ndiyeno kuchitapo kanthu ndi sodium fluoride kupeza 5-bromo-3-fluoropyridine.
Zambiri Zachitetezo:
- 5-Bromo-3-fluoropyridine ndi organic pawiri yomwe ndi yowopsa ndipo imafuna kusamalidwa bwino mu labotale.
- Zingakhale ndi zotsatira zokhumudwitsa m'maso ndi pakhungu ndipo kukhudzana mwachindunji kuyenera kupewedwa.
- 5-Bromo-3-fluoropyridine iyenera kusungidwa mu chidebe chopanda mpweya, kutali ndi moto ndi kutentha kwakukulu.
- Mukamagwiritsa ntchito ndikugwira, tsatirani njira zoyendetsera chitetezo ndikukhala ndi zida zodzitetezera zoyenera monga magolovesi ndi magalasi.
