Intangiriro
5-Bromo-3-fluoropyridine ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gutegura namakuru yumutekano:
Ubwiza:
- 5-Bromo-3-fluoropyridine nigikomeye hamwe na morphologie ya kirisiti yera cyangwa umuhondo.
- Nibintu bya organohalogen hamwe nibikorwa byinshi bya shimi.
- 5-Bromo-3-fluoropyridine ntishobora gushonga mumazi mubushyuhe bwicyumba, ariko irashonga mumashanyarazi kama nka Ethanol na ethers.
Koresha:
- 5-Bromo-3-fluoropyridine ikoreshwa kenshi nka reagent yingenzi muri synthesis.
- Ifite imbaraga zo gusimbuza amashanyarazi no kuyikora, kandi irashobora gukoreshwa mugusimbuza, guhuza hamwe no kuzunguruka muburyo bwa synthesis synthesis.
Uburyo:
- 5-Bromo-3-fluoropyridine irashobora guhuzwa nuburyo butandukanye, uburyo bukunze kugaragara ni ugukora bromofluoropyridine hamwe na acetonitrile.
- 3-Bromopyridine irashobora kandi kuboneka ubanza kwitwara hamwe na lithium subbromide kugirango itange 3-bromopyridine, hanyuma ikore hamwe na sodium fluoride kugirango ubone 5-bromo-3-fluoropyridine.
Amakuru yumutekano:
- 5-Bromo-3-fluoropyridine ni urugingo ngengabuzima ruteye akaga kandi rusaba gufata neza muri laboratoire.
- Irashobora kugira ingaruka mbi kumaso no kuruhu kandi tugomba kwirinda guhura.
- 5-Bromo-3-fluoropyridine igomba kubikwa mu kintu cyumuyaga, kure yumuriro nubushyuhe bwinshi.
- Mugihe ukoresha no gutunganya, kurikiza uburyo bukoreshwa mubikorwa byumutekano kandi ube ufite ibikoresho birinda umutekano nka gants na gogles.
