3 5-DIBROMO-2-FLUOROPYRIDINE(CAS# 473596-07-5)
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R25 – Kunobuthi uma ugwinywe |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) |
| I-Hazard Class | I-IRRITANT |
Isingeniso
I-3,5-Dibromo-2-fluoropyridine iyinhlanganisela ye-organic ene-chemical formula C5H2Br2FN. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
- I-3,5-Dibromo-2-fluoropyridine iyinhlanganisela eqinile enokubonakala kwekristalu emhlophe.
-Indawo yokuncibilika kwayo ingu-74-76 ℃, futhi indawo yayo yokubila ingu-238-240 ℃.
-Ayincibiliki emanzini ngamazinga okushisa asekamelweni, kodwa ingancibilika kwezinye izincibilikisi eziphilayo njenge-ether ne-ethanol.
Sebenzisa:
- I-3,5-Dibromo-2-fluoropyridine iyinhlanganisela ebalulekile ephakathi esetshenziswa kabanzi ekuphenduleni kwe-organic synthesis.
-Ingasetshenziswa njengempahla eluhlaza yezinto ezibonakalayo ze-photovoltaic, futhi ingasetshenziswa ukulungisa imithi, odayi kanye nezibulala-zinambuzane.
Indlela Yokulungiselela:
- I-3,5-Dibromo-2-fluoropyridine ingalungiswa ngokusabela kwe-pyridine iodide ne-curous bromide.
-Qala ngokuncibilikisa i-cuprous bromide ne-pyridine iodide ku-dimethyl sulfoxide ekamelweni lokushisa ukuze wenze into esabelayo, bese wengeza kancane kancane i-fluoride eyisiliva eyehlayo ekushiseni okuphansi, bese ekugcineni ushise kuze kuqedwe ukusabela.
Ulwazi Lokuphepha:
- I-3,5-Dibromo-2-fluoropyridine iyacasula isikhumba namehlo, futhi izinyathelo zokuzivikela kufanele zinakwe lapho uthintana.
-Naka umoya omuhle lapho usebenzisa lesi sithako.
-Ibola ekushiseni okuphezulu kuzokhiqiza amagesi ayingozi, futhi kuyadingeka ukugwema ukuchayeka emalangabi avulekile noma izindawo zokushisa eziphakeme.
-Kugcine ngendlela evalekile futhi ugweme ukuthintana nama-oxidants nama-acids aqinile ukuze ugweme ukusabela okuyingozi.
