Intshayelelo
I-2-Methylthio-3-methylpyrazine i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
1. Ukubonakala: I-2-methylthio-3-methylpyrazine ngokuqhelekileyo imhlophe eqinile okanye i-crystalline, kwaye ingaba nefom yepowder.
2. Ukunyibilika: Kunyibilika kwizinyibilikisi ezininzi eziphilayo ezifana nekloroform, benzene, kunye ne-ethanol.
Sebenzisa:
1. Amayeza okubulala izitshabalalisi: I-2-methylthio-3-methylpyrazine ingasetyenziswa njengezibulali ntsholongwane zokungunda kunye nezitshabalalisi, kwaye inempembelelo entle yokulawula ukungunda kunye nezinambuzane kwizityalo ezithile.
2. Ikhemistri yaselwandle: Le khompawundi ingasetyenziswa kuphando lwaselwandle ukufunda indlela yokuziphatha kunye neempendulo zephysiological zezinto eziphila elwandle.
Indlela:
I-2-Methylthio-3-methylpyrazine inokwenziwa ngala manyathelo alandelayo:
1. I-Condensate methyl thiocyanate kunye ne-acetone phantsi kweemeko ezifanelekileyo ukwenza i-Kawasaki heterocycles.
Emva koko, i-heterocycle ye-Kawasaki iphendulwa nge-asidi ye-formic ukunika i-2-methylthio-3-methylpyrazine.
Ulwazi ngoKhuseleko:
1. I-2-Methylthio-3-methylpyrazine inomphumo ophazamisayo kwaye kufuneka igwenywe ekudibaneni nolusu kunye namehlo.
2. Izixhobo ezifanelekileyo zokukhusela ezifana neeglavu kunye neglavu kufuneka zinxitywe xa usebenzisa okanye ukuphatha.
3. Ukuba ukuphefumla okanye ukutyile, funa unyango ngokukhawuleza.
