Mawu Oyamba
2-Methylthio-3-methylpyrazine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
1. Maonekedwe: 2-methylthio-3-methylpyrazine nthawi zambiri imakhala yoyera yolimba kapena crystalline, ndipo ingakhalenso mu mawonekedwe a ufa.
2. Kusungunuka: Amasungunuka mu zosungunulira zambiri monga chloroform, benzene, ndi ethanol.
Gwiritsani ntchito:
1. Mankhwala ophera tizirombo: 2-methylthio-3-methylpyrazine atha kugwiritsidwa ntchito ngati mankhwala ophera fungal ndi ophera tizirombo, ndipo ali ndi mphamvu yothana ndi mafangasi ndi tizirombo pa mbewu zina.
2. Chemistry ya m'madzi: Kapangidwe kameneka kangagwiritsidwenso ntchito pofufuza za m'madzi kuti muphunzire za momwe zamoyo za m'madzi zimakhalira komanso momwe thupi limayankhira.
Njira:
2-Methylthio-3-methylpyrazine ikhoza kupangidwa ndi njira zotsatirazi:
1. Condensate methyl thiocyanate ndi acetone pansi pamikhalidwe yoyenera kupanga Kawasaki heterocycles.
Kenako, heterocycle ya Kawasaki imachitidwa ndi formic acid kuti ipereke 2-methylthio-3-methylpyrazine.
Zambiri Zachitetezo:
1. 2-Methylthio-3-methylpyrazine imakhala ndi zotsatira zokhumudwitsa ndipo iyenera kupeŵedwa kuti isagwirizane ndi khungu ndi maso.
2. Zida zodzitetezera zoyenera monga magolovesi ndi magalasi ayenera kuvala pogwiritsira ntchito kapena pogwira.
3. Mukakokedwa kapena kumeza, pitani kuchipatala mwamsanga.
