Taw qhia

2-methylpyridine yog ib qho organic compound. Nws yog cov xim tsis muaj xim rau daj ntseg daj nrog cov tsw zoo li pyridine.

 

2-Methylpyrazine feem ntau yog siv rau hauv cov organic synthesis ua reagent, hnyav thiab nruab nrab. Nws tuaj yeem siv los ua ligand rau catalysts rau cov tshuaj tiv thaiv hlau-catalyzed.

 

Muaj ntau txoj hauv kev rau kev npaj ntawm 2-methylpyrazine, ib qho ntawm feem ntau siv yog cov tshuaj tiv thaiv ntawm 2-aminopyrazine nrog methylation reagents xws li methyl iodide. Cov kev sib txuas tshwj xeeb kuj suav nrog cyanide hydrogenation thiab halogenation ntawm halogenation.

Thaum ua haujlwm, kev ntsuas cua zoo yuav tsum tau ua kom tsis txhob nqus pa los yog sib cuag ntawm daim tawv nqaij thiab qhov muag. Tsis txhob sib cuag nrog cov oxidants muaj zog thiab cov kua qaub kom tsis txhob muaj kev phom sij txaus ntshai. Nyob rau hauv rooj plaub ntawm kev sib chwv los yog nqus tau pa, nrhiav kev kho mob tam sim ntawd.
