2-methylpyridine ke motsoako oa lintho tse phelang. Ke mokelikeli o mosehla o se nang 'mala ho isa ho o mosehla o nang le monko o kang oa pyridine.

 

2-Methylpyrazine e atisa ho sebelisoa ho organic synthesis e le reagent, solvent le intermediate. E ka sebelisoa e le ligand bakeng sa li-catalysts bakeng sa karabelo ea tšepe-catalyzed.

 

Ho na le mekhoa e fapaneng ea ho lokisoa ha 2-methylpyrazine, e 'ngoe ea tse sebelisoang haholo ke karabelo ea 2-aminopyrazine ka li-reagents tsa methylation tse kang methyl iodide. Mekhoa e khethehileng ea ho kopanya e boetse e kenyelletsa cyanide hydrogenation le halogenation ea halogenation.

Ha o sebetsa, mehato e metle ea moea e lokela ho nkoa ho qoba ho hema likhase kapa ho kopana le letlalo le mahlo. Qoba ho kopana le li-oxidants tse matla le li-acid ho thibela liketso tse kotsi. Haeba motho a kopane kapa a hema ka phoso, batla thuso ea bongaka hang-hang.
