Selelekela
5-Bromo-3-fluoropyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:
Boleng:
- 5-Bromo-3-fluoropyridine ke ntho e tiileng e nang le morphology ea likristale tse tšoeu kapa tse mosehla.
- Ke motsoako oa organohalogen o nang le ts'ebetso e phahameng ea lik'hemik'hale.
- 5-Bromo-3-fluoropyridine ha e qhibilihe ka metsing ka mocheso oa kamore, empa e qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le ethers.
Sebelisa:
- 5-Bromo-3-fluoropyridine hangata e sebelisoa e le reagent ea bohlokoa ho organic synthesis.
- E na le phetoho e matla ea electrophilic le ts'ebetso, 'me e ka sebelisoa bakeng sa phetisetso, coupling le cyclization karabelo ea organic synthesis.
Mokhoa:
- 5-Bromo-3-fluoropyridine e ka etsoa ka mekhoa e fapaneng, mokhoa o tloaelehileng haholo ke ho itšoara ka bromofluoropyridine ka acetonitrile.
- 3-Bromopyridine e ka boela ea fumanoa ka ho qala ho itšoara ka lithium subbromide ho hlahisa 3-bromopyridine, ebe e itšoara ka sodium fluoride ho fumana 5-bromo-3-fluoropyridine.
Lintlha tsa Tšireletseho:
- 5-Bromo-3-fluoropyridine ke motsoako oa tlhaho o kotsi 'me o hloka ho tšoaroa ka mokhoa o sireletsehileng ka laboratoring.
- E ka 'na ea e-ba le phello e khopisang mahlong le letlalong' me ho kopana ka ho toba ho lokela ho qojoa.
- 5-Bromo-3-fluoropyridine e lokela ho bolokoa ka setsing se se nang moea, hole le mollo le mocheso o phahameng.
- Ha o sebelisa le ho tšoara, latela mekhoa e nepahetseng ea ts'ebetso ea ts'ireletso 'me u be le lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka liatlana le likhalase.
