Selelekela
2-Bromo-4-methyl-5-nitropyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:
Boleng:
2-Bromo-4-methyl-5-nitropyridine ke ntho e tiileng e nang le likristale tse mosehla. Mocheso oa kamore, ha se hangata o qhibilihang ka metsing, empa o ka qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le dimethylformamide.
Sebelisa:
Motsoako ona o atisa ho sebelisoa e le setsi sa organic synthesis. E ka sebelisoa ha ho lokisoa metsoako e meng ea heterocyclic e nang le naetrojene, joalo ka pyrroles le indoles.
Mokhoa:
2-Bromo-4-methyl-5-nitropyridine e ka lokisoa ke karabelo ea sebaka sa aniline. Tlas'a maemo a loketseng, aniline e sebetsanoa le asiti ea bromoacetic ho hlahisa 2-bromoaniline. Joale, ka alkylation tlas'a maemo a alkaline, 2-bromoaniline e alkylated ho fumana 2-bromo-4-methylaniline. Sephetho sa 2-bromo-4-methylaniline se naetrification ka nitrification ho fumana 2-bromo-4-methyl-5-nitropyridine.
Lintlha tsa Tšireletseho:
2-Bromo-4-methyl-5-nitropyridine ke motsoako oa tlhaho 'me o lokela ho bolokoa le ho sebelisoa ka nepo. Ke ntho e tukang mme e lokela ho bewa hole le malakabe a bulehileng le mocheso o phahameng. Nakong ea ts'ebetso, ho kopana le letlalo, mahlo, le pampiri ea ho hema ho lokela ho qojoa, 'me ts'ebetso e lokela ho etsoa tlas'a maemo a moea. Liatlana tse sireletsang, likhalase le limaske li lokela ho apesoa ha li sebelisoa. Haeba ho ka etsahala hore u kopane ka phoso, hlatsoa hang-hang ka metsi a mangata 'me u batle ngaka.
