3-AMINO-2-BROMO-5-CHLOROPYRIDINE(CAS# 90902-83-3)
| Amakhodi Engozi | I-R22 – Iyingozi uma igwinywe R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okubi emehlweni |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S39 – Gqoka ukuvikela iso / ubuso. |
| Inothi Lengozi | Iyacasula |
Isingeniso
Kuyinhlanganisela ye-organic ifomula yayo yamakhemikhali ithi C5H4BrClN2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: Kuqinile crystalline emhlophe.
-Iphuzu elincibilikayo: Ibanga lalo lokuncibilika lingama-58-62 degrees Celsius.
-Ukunyibilika: Kuncibilika kuzincibilikisi ezivamile zemvelo (njenge-ethanol, i-dimethyl sulfoxide ne-dimethyl formamide).
Sebenzisa:
-m ingasetshenziswa njengendawo ephakathi ku-organic synthesis ukuze kuhlanganiswe ezinye izinhlanganisela eziphilayo.
-Ingasetshenziswa futhi njengento ebalulekile emkhakheni wezibulala-zinambuzane kanye nemithi.
Indlela: Ukulungiswa kwe
-noma ingatholakala ku-pyridine njenge-compound yokuqala futhi ngokusebenzisa uchungechunge lokusabela kwamakhemikhali.
-Indlela ethile yokulungiselela iyahlukahluka kuye ngezimo ezihlukene, futhi ingalungiswa ngokusabela kwe-amination, bromination and chlorination.
Ulwazi Lokuphepha:
-kungase kube yingozi empilweni yomuntu, kufanele kuqikelelwe ukugwema ukuhogela, ukuthintana noma ukungenwa.
-Izimpahla zokuzivikela ezinjengamagilavu, izibuko kanye nezihlangu zobuso kufanele zigqokwe ngesikhathi sokusebenza.
-Uma unesifiso noma ukuchayeka kulesi sithako, funa usizo lwezempilo ngokushesha noma usizo lukachwepheshe olawula ubuthi.
-Ngesikhathi sokugcina nokuphatha, sicela ulandele zonke izinqubo zokuphepha nemithethonqubo ukuze uqinisekise ukusetshenziswa okuphephile kwenhlanganisela.
