Mawu Oyamba
2-Methylthiopyrazine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-methylthiopyrazine:
Ubwino:
- 2-Methylthiopyrazine ndi kristalo wachikasu wonyezimira kapena ufa wa crystalline wokhala ndi fungo lochepa la sulfure.
- Ndi zamchere zikasungunuka m'madzi ndipo zimatha kusungunuka muzitsulo zonse za acidic ndi zamchere.
- Ikatenthedwa kapena kuyatsa, 2-methylthiopyrazine imatulutsa mpweya wapoizoni.
Gwiritsani ntchito:
- 2-Methylthiopyrazine imagwiritsidwa ntchito kwambiri popanga mankhwala monga chothandizira kapena ligand pazochita za organic synthesis.
Njira:
- Kukonzekera kwa 2-methylthiopyrazine nthawi zambiri kumachitika ndi zomwe sulfide ndi 2-chloropyridine. Gawo lenileni ndikuchita 2-chloropyridine ndi sodium sulfide mu zosungunulira organic kupeza mankhwala a 2-methylthiopyrazine.
Zambiri Zachitetezo:
- 2-Methylthiopyrazine ndi mankhwala oopsa ndipo ayenera kupewedwa pokoka mpweya, kuyamwa, kapena kukhudzana ndi khungu ndi maso.
- Zida zodzitetezera zoyenerera monga magolovesi, magalasi a maso, ndi mikanjo ziyenera kuvalidwa panthawi yomwe mukugwiritsa ntchito kapena kukonzekera.
- Iyenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino kuti mpweya wake usapitirire malire otetezedwa.
- Posunga, iyenera kukhala yosindikizidwa mwamphamvu, kutali ndi moto ndi ma oxidants.
- Zikakhudzana mwangozi kapena kumeza, pitani kuchipatala mwachangu.
