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

Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali C5H3BrN2O3. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:

Imvelo:

-Ukubukeka: I-Crystal iyimpushana ephuzi ukuya kuwolintshi.

-Iphuzu lokuncibilika nendawo yokubilisa: Iphuzu lokuncibilika lenhlanganisela lingaba ngu-141-144°C, futhi indawo yokubilisa ayaziwa.

-Ukunyibilika: Ine-solubility ephansi emanzini futhi ingancibilika kuzincibilikisi zemvelo ezifana ne-chloroform, i-methanol ne-ether.

Sebenzisa:

-iwusizo njenge-intermediate in organic synthesis. Ingasetshenziswa njengezinto zokwenziwa zokwenziwa zezidakamizwa, izibulala-zinambuzane nezinye izinhlanganisela.

Indlela Yokulungiselela:

-noma ingalungiswa ngokuphendula i-pyridine nge-bromoacetic acid, bese yenza ukusabela kwe-nitrate ngaphansi kwezimo ze-alkali.

Ulwazi Lokuphepha:

-ingaba yingozi empilweni lapho ithinta isikhumba, amehlo noma ngokuhogela. Ukuhogela uthuli nokuxhumana nesikhumba kufanele kugwenywe. Gqoka izinto zokuzivikela ezifanele ngesikhathi sokusetshenziswa.

-Gwema ukuthintana nama-oxidants aqinile, ama-asidi aqinile nezinye izinto ngesikhathi sokugcina nokuphatha ukuze ugweme ukusabela okuyingozi.

-Lapho usebenzisa futhi uphatha inhlanganisela, landela izinqubo ezifanele zaselabhorethri kanye nezinqubo zokusebenza eziphephile.
