4-Bromo-2-methylpyridine (CAS# 22282-99-1)
| Amakhodi Engozi | I-R22 – Iyingozi uma igwinywe R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okubi emehlweni 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. S36/39 - S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
I-2-Methyl-4-bromopyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-methyl-4-bromopyridine:
Ikhwalithi:
- I-2-Methyl-4-bromopyridine iqinile engenambala ukuya kokuphuzi okuphaphathekile.
- I-2-Methyl-4-bromopyridine icishe ingancibiliki emanzini kodwa incibilika kuzincibilikisi zemvelo.
Sebenzisa:
- I-2-Methyl-4-bromopyridine ingasetshenziswa njengento eluhlaza kanye ne-reagent ku-organic synthesis.
Indlela:
- I-2-Methyl-4-bromopyridine ingatholakala ngokusabela i-2-methyl-4-pyridine methanol nge-phosphorus tribromide.
- Ngesikhathi sokuphendula, i-2-methyl-4-pyridine methanol ne-phosphorus tribromide yengezwe emkhunjini wokusabela, ingxube yokusabela yashiswa, bese i-2-methyl-4-bromopyridine ihlanjululwa yi-distillation nezinye izindlela.
Ulwazi Lokuphepha:
- I-2-Methyl-4-bromopyridine ingabangela ukucasuka kwamehlo, isikhumba, nokuphefumula futhi kufanele kugwenywe uma isetshenziswa.
- Gqoka izingubo zamehlo ezivikelayo, amagilavu nokuvikela ukuphefumula lapho usebenzisa.
- Kuyinto enobuthi futhi kufanele igcinwe kahle futhi igcinwe kude nemithombo yomlilo kanye nama-oxidizing agents.
- Uma i-2-methyl-4-bromopyridine ihogelwe noma idliwe, funa usizo lwezokwelapha ngokushesha.
