Okwu mmalite
5-Bromo-3-fluoropyridine bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, usoro nkwadebe na ozi nchekwa ya:
Ogo:
- 5-Bromo-3-fluoropyridine bụ ihe siri ike na morphology nke kristal ọcha ma ọ bụ odo odo.
- Ọ bụ ihe organohalogen nwere ọrụ kemịkal dị elu.
- 5-Bromo-3-fluoropyridine bụ ihe a na-adịghị ahụkebe na mmiri na ụlọ okpomọkụ, ma soluble na organic solvents dị ka ethanol na ethers.
Jiri:
A na-ejikarị 5-Bromo-3-fluoropyridine eme ihe dị ka reagent dị mkpa na njikọ organic.
- Ọ nwere ike electrophilic nnọchi na ịgbalite, na ike ga-eji maka nnọchi, njikọ na cyclization mmeghachi omume na organic njikọ mmeghachi omume.
Usoro:
- 5-Bromo-3-fluoropyridine nwere ike ịmepụta site na ụzọ dị iche iche, usoro a na-emekarị bụ imeghachi bromofluoropyridine na acetonitrile.
- 3-Bromopyridine nwekwara ike nweta site na mbụ meghachi omume na lithium subbromide iji mepụta 3-bromopyridine, wee meghachi omume na sodium fluoride iji nweta 5-bromo-3-fluoropyridine.
Ozi nchekwa:
- 5-Bromo-3-fluoropyridine bụ ngwakọta organic nke dị ize ndụ ma chọọ njikwa nchekwa na ụlọ nyocha.
- O nwere ike inwe mmetụta na-akpasu iwe na anya na akpụkpọ ahụ na kọntaktị kwesịrị izere.
- 5-Bromo-3-fluoropyridine kwesịrị ịchekwa n'ime akpa ikuku, pụọ na ọkụ na oke okpomọkụ.
- Mgbe ị na-eji na njikwa, soro usoro ọrụ nchekwa dị mkpa ma nweekwa akụrụngwa nchedo kwesịrị ekwesị dịka uwe aka na anya.
