Folasaga
2-Methylthiopyrazine o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, auala sauniuni ma faʻamatalaga saogalemu o le 2-methylthiopyrazine:
Tulaga lelei:
- 2-Methylthiopyrazine e leai se lanu e malamalama i tioata samasama poʻo se paʻu tioata ma se manogi vaivai o le sulfur.
- E alkaline pe a fa'amavae i le vai ma e mafai ona fa'amavae i vaifofo fa'ama'i ma alkaline.
- Pe a faʻavevela pe faʻamumu, 2-methylthiopyrazine faʻasaʻoloto kasa oona.
Fa'aaogā:
- 2-Methylthiopyrazine o loʻo faʻaaogaina lautele i vailaʻau faʻapipiʻi e avea o se faʻamalosi poʻo se ligand mo faʻasologa faʻasologa o meaola.
Metotia:
- O le sauniuniga o le 2-methylthiopyrazine e masani lava ona maua i le tali atu o le sulfide ma le 2-chloropyridine. O le laasaga faʻapitoa o le tali atu lea i le 2-chloropyridine ma le sodium sulfide i totonu o se solvent organic e maua ai le oloa o le 2-methylthiopyrazine.
Fa'amatalaga Saogalemu:
- 2-Methylthiopyrazine ose vailaʻau oona ma e tatau ona aloese mai le inhalation, ingestion, poʻo le faʻafesoʻotaʻi ma le paʻu ma mata.
- O mea faigaluega puipuia e pei o totigilima, mata tioata, ma ofu talaloa e tatau ona ofuina a'o fa'aoga po'o sauniuniga.
- E tatau ona fa'aogaina i totonu o se nofoaga fa'alelei lelei ina ia 'alofia ai le fa'aogaina o le ausa e sili atu i le tapulaa saogalemu.
- Pe a teuina, e tatau ona faʻamaufaʻailogaina, mamao ese mai afi ma mea faʻamaʻi.
- Pe a fa'afuase'i ona fa'afeso'ota'i po'o le inuina, saili vave togafitiga faafoma'i.
