2-Chloro-3-bromo-4-methylpyridine (CAS# 55404-31-4)

Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali ye-C6H5BrClN kanye nesisindo semolekyuli esingu-192.48g/mol. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:

1. imvelo:

-Ukubukeka: uketshezi oluphuzi olukhanyayo olungenambala noma oluqinile;

Iphuzu elibilayo: mayelana ne-220-222 ℃ (nge-barometer);

-indawo yokuncibilika: mayelana ne-33-35 ℃;

-Izwela ekukhanyeni, gwema ukuchayeka elangeni isikhathi eside;

-Incibilika kuzincibilikisi ezivamile ezifana ne-ethanol ne-dimethylformamide.

2. sebenzisa:

-Njenge-intermediate: ingasetshenziswa ukulungisa ezinye izinhlanganisela, ezifana ne-fluorine-containing compounds noma i-derivatives yamanye ama-heterocyclic compounds;

-Isetshenziswa ku-organic synthesis: Ingasetshenziswa njenge-reagent ebalulekile ku-organic synthesis ukwethula amaqembu asebenzayo njengama-athomu e-halogen noma amaqembu e-amino.

3. Indlela yokulungiselela:

-Ngokuvamile ingalungiswa ngenhlanganisela ye-chlorination, bromination kanye ne-methylation ye-pyridine.

4. Ulwazi Lokuphepha:

-i-organic compound, engase ibe yingozi;

-kufanele kuhambisane nezinqubo zokuphepha zamakhemikhali zokusebenza, ukugwema ukuthintana ngqo nesikhumba namehlo;

-Ukungena komoya okuhle kufanele kuhlinzekwe ngesikhathi sokusetshenziswa ukuze kugwenywe ukuhogela umhwamuko;

-Ukulahla imfucuza, hambisana nemithetho yendawo.
