Isingeniso

I-3,5-Dibromo-2-methoxypyridine (eyaziwa nangokuthi i-2-bromo-3, 5-dimethoxypyridine) iyinhlanganisela yezinto eziphilayo. Ine-molecular formula ye-C7H6Br2NO kanye nesisindo se-molecular 264.94g/mol.3,5-Dibromo-2-methoxypyridine iqinile enamakristalu amhlophe kuya kokuphuzi okuphaphathekile. Ingancibilika kwezinye izinyibilikisi eziphilayo ekamelweni lokushisa, njenge-chloroform, i-ether kanye ne-methanol.Ukusetshenziswa okuyinhloko kwalesi sakhi kufana ne-intermediate kanye ne-reagent ku-organic synthesis. Ingasetshenziselwa ukuhlanganisa imithi ehlukahlukene, izibulala-zinambuzane, odayi nezinye izinhlanganisela eziphilayo.

Indlela yokukhiqiza i-3,5-dibromo-2-methoxypyridine ivame ukutholakala ngokusabela ku-3,5-dibromopyridine nge-methanol. Izimo zokusabela zingenziwa ngaphansi komkhathi ongasebenzi ezingeni lokushisa elifanele kanye nesikhathi sokusabela.

Mayelana nolwazi lokuphepha, i-3,5-dibromo-2-methoxypyridine iyinto eyingozi. Kungase kubangele ukucasuka nokugqwala emzimbeni womuntu, futhi kungase kube yingozi endaweni ezungezile. Ngesikhathi sokusetshenziswa nokuphathwa, izinyathelo ezifanele zokuphepha kufanele zithathwe, njengokugqoka amagilavu okuzivikela, izibuko nezingubo zokuzivikela, ukuqinisekisa ukungena komoya okuhle, nokugwema ukuthintana nesikhumba namehlo. Ukwengeza, izindlela ezifanele zokugcina kanye nezindlela zokulahla zidinga ukuqinisekiswa ukuze kuvinjelwe izingozi nokungcoliswa. Ngaphambi kokusetshenziswa, kungcono ukubhekisela ephepheni ledatha yezokuphepha lamakhemikhali ukuze uthole ulwazi oluningiliziwe lokuphepha.
