2-Fluoro-5-bromo-3-methylpyridine (CAS# 29312-98-9)
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okubi emehlweni R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. S39 – Gqoka ukuvikela iso / ubuso. S37 – Gqoka amagilavu afanelekile. |
| Ikhodi ye-HS | 29339900 |
| I-Hazard Class | I-IRRITANT |
Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C7H6BrFN.
Imvelo:
-Ukubukeka: Uketshezi olungenambala oluphuzi olukhanyayo
-Indawo yokuncibilika: -3 ℃
-Indawo yokubilisa: 204-205 ℃
-Ukuminyana: 1.518g/cm³
-Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika kuzincibilikisi eziningi eziphilayo
Sebenzisa:
Isetshenziswa kakhulu ku-organic synthesis njengento ebalulekile ephakathi. Ingasetshenziselwa ukuhlanganisa izidakamizwa, izibulala-zinambuzane kanye nezinye izinhlanganisela eziphilayo.
Indlela:
Indlela yokulungiselela imi kanje:
1. Nge-2-fluoropyridine kanye nenani elithile le-methyl bromide phambi kwe-oxidant chlorine noma i-carbon peroxide reaction.
2. Ilungiselelwe ukusabela kwe-2-bromo-5-fluoropyridine ne-methyl lithium.
Ulwazi Lokuphepha:
Ingase icasule futhi idle umzimba womuntu, ngakho-ke udinga ukunaka izinyathelo zokuphepha lapho uyisebenzisa, okuhlanganisa ukugqoka amagilavu okuzivikela, izibuko nezingubo zokuzivikela. Gwema ukuhogela umhwamuko wayo noma ukuthinta isikhumba namehlo. Uma uhogelwe noma uvezwe enkomponi, geza indawo ethintekile ngokushesha futhi ufune usizo lwezokwelapha uma kunesidingo.
