Nhanganyaya
2-Methylthiopyrazine isanganiswa yeorganic. Izvi zvinotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2-methylthiopyrazine:
Hunhu:
- 2-Methylthiopyrazine ikristaro isina ruvara kune yero kana crystalline poda ine kunhuhwirira kwesarufa isina simba.
- Iyo alkaline kana yakanyungudutswa mumvura uye inogona kunyungudutswa mune zvese acidic uye alkaline mhinduro.
- Kana ichipisa kana kupisa, 2-methylthiopyrazine inoburitsa magasi ane chepfu.
Shandisa:
- 2-Methylthiopyrazine inoshandiswa zvakanyanya mumakemikari synthesis sechinhu chinokonzera kana kuti ligand ye organic synthesis reactions.
Nzira:
- Kugadzirira kwe2-methylthiopyrazine kunowanzo kuwanikwa nekuita kwe sulfide ne 2-chloropyridine. Nhanho chaiyo ndeyekuita 2-chloropyridine ne sodium sulfide mune organic solvent kuti uwane chigadzirwa che 2-methylthiopyrazine.
Zvekuchengetedza
- 2-Methylthiopyrazine mushonga une chepfu uye unofanirwa kudzivirirwa kubva mukufemerwa, kupinza, kana kusangana neganda nemeso.
- Midziyo yekuzvidzivirira yakafanira senge magirovhosi, magirazi emaziso, uye magauni anofanira kupfekwa panguva yekushandiswa kana kugadzirira.
-Inofanirwa kushandiswa munzvimbo ine mhepo inofefetera zvakanaka kudzivirira iyo vapor concentration inodarika chengetedzo.
- Paunenge uchichengeta, inofanira kuchengetwa yakavharwa zvakasimba, kure nemoto uye oxidants.
- Kana wasangana netsaona kana kupinza, tsvaga kurapwa nekukurumidza.
