6-Bromo-2-nitro-pyridin-3-ol (CAS# 443956-08-9)

Intshayelelo

I-organic compound kunye ne-chemical formula C5H3BrN2O3. Oku kulandelayo yinkcazo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwekhompawundi:

Indalo:

-Inkangeleko: ICrystal ngumgubo omthubi ukuya kwe-orenji.

-Indawo yokuncibilika kunye neyokubilisa: Indawo encibilikayo ye-compound i malunga ne-141-144 ° C, kwaye indawo yokubilisa ingaziwa.

-I-Solubility: Ine-solubility ephantsi emanzini kwaye inokunyibilika kwii-solvents eziphilayo ezifana ne-chloroform, i-methanol kunye ne-ether.

Sebenzisa:

-iluncedo njengento ephakathi kwi-organic synthesis. Ingasetyenziswa njengento ekrwada yokwenziwa kumachiza, amayeza okubulala izitshabalalisi kunye nezinye iikhompawundi.

Indlela yokulungiselela:

-okanye inokulungiswa ngokuphendula i-pyridine nge-bromoacetic acid, kwaye emva koko yenza i-nitration reaction phantsi kweemeko ze-alkaline.

Ulwazi ngoKhuseleko:

-inokuba yingozi empilweni xa udibana nolusu, amehlo okanye ngokuphefumla. Ukuphefumla uthuli kunye nokudibanisa nolusu kufuneka kugwenywe. Nxiba izixhobo ezifanelekileyo zokuzikhusela xa uzisebenzisa.

-Gwema ukudibana nee-oxidants ezinamandla, i-acids eqinile kunye nezinye izinto ngexesha lokugcinwa kunye nokuphatha ukuphepha ukuphendula okuyingozi.

-Xa usebenzisa kwaye uphatha ikhompawundi, landela iindlela ezichanekileyo zebhubhoratri kunye neenkqubo zokusebenza ezikhuselekileyo.
