Isingeniso
I-5-Bromo-3-fluoropyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- I-5-Bromo-3-fluoropyridine iqinile ene-morphology yamakristalu amhlophe noma aphuzi.
- Kuyinhlanganisela ye-organohalogen enomsebenzi wamakhemikhali aphezulu.
- I-5-Bromo-3-fluoropyridine ayincibiliki emanzini ekamelweni lokushisa, kodwa incibilika kuzincibilikisi eziphilayo njenge-ethanol nama-ether.
Sebenzisa:
- I-5-Bromo-3-fluoropyridine ivame ukusetshenziswa njenge-reagent ebalulekile ku-organic synthesis.
- Inokushintshaniswa okuqinile kwe-electrophilic kanye nokwenza kusebenze, futhi ingasetshenziselwa ukufaka esikhundleni, ukuhlanganisa kanye nokusabela kwamabhayisikili ekuphenduleni kwe-organic synthesis.
Indlela:
- I-5-Bromo-3-fluoropyridine ingahlanganiswa ngezindlela ezahlukene, indlela evame kakhulu ukusabela nge-bromofluoropyridine nge-acetonitrile.
- I-3-Bromopyridine ingabuye itholakale ngokuqala ngokusabela nge-lithium subbromide ukukhiqiza i-3-bromopyridine, bese isabela nge-sodium fluoride ukuze ithole i-5-bromo-3-fluoropyridine.
Ulwazi Lokuphepha:
- I-5-Bromo-3-fluoropyridine iyinhlanganisela yemvelo eyingozi futhi edinga ukuphathwa okuphephile elabhorethri.
- Kungase kube nomphumela ocasulayo emehlweni nasesikhumbeni futhi ukuthintana ngqo kufanele kugwenywe.
- I-5-Bromo-3-fluoropyridine kufanele igcinwe esitsheni esingangeni moya, kude nomlilo kanye namazinga okushisa aphezulu.
- Lapho usebenzisa futhi uphatha, landela izinqubo ezifanele zokusebenza zokuphepha futhi uhlonyiswe ngezinto zokuvikela ezifanele njengamagilavu nezibuko.
