2. Solubility: Inonyungudika muzvinonyungudutsa zvakawanda zvakaita sechloroform, benzene, uye ethanol.

 

Shandisa:

1. Mishonga yezvipembenene: 2-methylthio-3-methylpyrazine inogona kushandiswa sefungicides uye mishonga yezvipembenene, uye ine simba rakanaka rekutonga kune fungi uye zvipembenene pane zvimwe zvirimwa.

2. Marine chemistry: Mushonga uyu unogona kushandiswawo kutsvagiridzo yemugungwa kuti udzidze maitiro uye mhinduro dzemuviri wezvipenyu zvemugungwa.

 

Nzira:

2-Methylthio-3-methylpyrazine inogona kugadzirwa nematanho anotevera:

1. Condensate methyl thiocyanate uye acetone pasi pemamiriro akakodzera kuti aumbe Kawasaki heterocycles.

Zvadaro, iyo Kawasaki heterocycle inobatwa nefomic acid kuti ipe 2-methylthio-3-methylpyrazine.

 

Zvekuchengetedza

1. 2-Methylthio-3-methylpyrazine ine simba rinoshungurudza uye inofanira kudziviswa kubva pakusangana neganda nemaziso.

2. Midziyo yekudzivirira yakakodzera yakadai semagirovhosi nemagogi inofanira kupfekwa pakushandisa kana kubata.

3. Kana ukafema kana ukamwisa, tsvaga kurapwa nekukurumidza.
