2-Fluoro-3-chloro-5-bromopyridine wani abu ne na halitta.
Filin yana da ƙarfi tare da farin zuwa haske rawaya bayyanar crystalline. Ba shi da narkewa a cikin ruwa a yanayin zafi, amma yana iya zama mai narkewa a cikin wasu kaushi na halitta kamar methanol da methylene chloride.
3-Bromo-5-chloro-6-fluoropyridine yana da ƙayyadaddun ƙimar aikace-aikacen a cikin haɗin kwayoyin halitta. Yawancin lokaci ana amfani da shi azaman tsaka-tsaki don halayen daban-daban a cikin haɗaɗɗun kwayoyin halitta, kamar halayen haɗakarwa da halayen aikin aikin hydrocarbon aromatic. Wadannan halayen zasu iya taka muhimmiyar rawa wajen gina hadadden tsarin kwayoyin halitta.
Hanyar shirya 3-bromo-5-chloro-6-fluoropyridine za a iya aiwatar da shi ta hanyoyi daban-daban. Hanyar gama gari ita ce aiwatar da matakin halogenation mataki ta hanyar abubuwan da suka dace na pyridine, fara gabatar da fluorine a matsayi na 3, sannan chlorine a matsayi na 5, sannan a ƙarshe bromine a matsayi na 6.
Bayanin aminci: 3-Bromo-5-chloro-6-fluoropyridine sinadari ne kuma yakamata a sarrafa shi daidai da hanyoyin aiki na aminci masu dacewa. Yana iya zama mai ban haushi ga fata, idanu, da fili na numfashi, kuma ya kamata a sanya kayan kariya masu dacewa kamar safar hannu, tabarau, da tufafin kariya lokacin aiki.
Hakanan ya kamata a gudanar da adanawa da sarrafa sinadarai daidai da ƙa'idodin da suka dace, kuma a rarraba su da lakafta su bisa ga kaddarorin zahiri na sinadarai. A cikin amfani, tabbatar da samun iska mai kyau kuma a guji shakar iskar gas ko tururi.
