I-3,5-Dibromo-2-methoxypyridine (eyaziwa nangokuthi i-2-bromo-3, i-5-dimethoxypyridine) i-organic compound. Ine-molecular formula ye-C7H6Br2NO kunye ne-molecular weight ye-264.94g / mol.3,5-Dibromo-2-methoxypyridine iqinile kunye neekristale ezimhlophe eziphuzi eziphuzi. Inokunyibilika kwezinye izinyibilikisi eziphilayo kwiqondo lokushisa, njengekloroform, i-ether kunye ne-methanol.Usetyenziso oluphambili lwale khompawundi luyi-intermediate and reagent in organic synthesis. Ingasetyenziselwa ukudibanisa amachiza ahlukeneyo, izitshabalalisi, iidayi kunye nezinye izinto eziphilayo.

Indlela yokuvelisa i-3,5-dibromo-2-methoxypyridine idla ngokufumaneka ngokuphendula i-3,5-dibromopyridine nge-methanol. Iimeko zokusabela zinokuqhutywa phantsi kwe-atmosphere ye-inert kwiqondo lokushisa elifanelekileyo kunye nexesha lokuphendula.

Ngokuphathelele ulwazi lokhuseleko, i-3,5-dibromo-2-methoxypyridine yinto enobungozi. Inokubangela ukucaphuka kunye nomhlwa emzimbeni womntu, kwaye inokuba yingozi kwindalo esingqongileyo. Ngexesha lokusetyenziswa kunye nokuphathwa, amanyathelo afanelekileyo okhuseleko kufuneka athathwe, njengokunxiba iiglavu zokukhusela, izibuko kunye nempahla yokukhusela, ukuqinisekisa ukungena komoya kakuhle, kunye nokuphepha ukudibana nolusu kunye namehlo. Ukongezelela, iindlela ezifanelekileyo zokugcina kunye neendlela zokulahla kufuneka ziqinisekiswe ukukhusela iingozi kunye nokungcoliswa. Ngaphambi kokusetyenziswa, kungcono ukubhekisa kwiphepha ledatha yokhuseleko lekhemikhali ngolwazi oluthe vetshe ngokhuseleko.
