2-Amino-5-bromo-3-nitropyridine (CAS# 6945-68-2)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S22 - Ungaphefumuli uthuli. |

Isingeniso
Kuyinhlanganisela yezinto eziphilayo. Inefomula yamakhemikhali ye-C5H3BrN4O2 kanye nesisindo se-molecular 213.01g/mol. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
-Ukubukeka: Kuyikristalu ephuzi kuya ku-orange noma impushana;
-Iphuzu lokuncibilika: mayelana ne-117-120 degrees Celsius;
-Ukunyibilika: Kuncibilika kancane emanzini futhi kuncibilika kwezinye izinyibilikisi zemvelo ezifana notshwala, ama-ester nama-ketone.
Sebenzisa:
-Drug synthesis: Ivamise ukusetshenziswa njengendawo emaphakathi ekuhlanganiseni kwezinto eziphilayo futhi ingasetshenziswa ukuhlanganisa izidakamizwa ezinhlobonhlobo, odayi, izibulala-zinambuzane nezinye izinhlanganisela.
Indlela Yokulungiselela:
Ziningi izindlela zokulungiselela, futhi okulandelayo kungenye yazo:
1. Okokuqala, i-3-bromo-5-nitropyridine isabela nge-ammonia ukuze ithole i-3-nitro-5-aminopyridine.
2. Umphumela we-3-nitro-5-aminopyridine ube ususabela nge-bromoalkane noma i-acetyl ukuze kutholwe umkhiqizo wokugcina.
Ulwazi Lokuphepha:
Ngokuvamile iphephile uma isetshenziswa futhi igcinwe ngendlela efanele. Nokho, kufanele kuthathwe izinyathelo zokuphepha ezilandelayo:
-Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko namajazi elebhu;
-Gwema ukuthinta isikhumba, umlomo kanye namehlo. Uma kukhona ukuthintana, hlambulula ngokushesha ngamanzi amaningi;
-Sebenzisa futhi ugcine inhlanganisela endaweni enomoya omuhle ukuze ugweme ukuhogela igesi noma uthuli;
-Ungagcini noma usebenzise inhlanganisela enezinto ezivuthayo;
-Funda ngokucophelela futhi ulandele imithetho yokuphepha kanye nokulahlwa kwemfucuza ngaphambi kokusetshenziswa noma ukulahlwa.
Sicela uqaphele ukuthi ulwazi oluhlinzekwe ngenhla olokubhekisela kuphela, futhi isimo esithile sidinga ukuqondwa kabanzi futhi siqinisekiswe ngokwezidingo zangempela.
