2-Mercapto Methyl Pyrazine（CAS#59021-02-2）

Folasaga

2-mercaptomethylpyrazine, e taʻua foi o le 2-mercaptopyrazine methane poʻo le methazole, o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, auala sauniuni ma faʻamatalaga saogalemu o le 2-mercaptomethylpyrazine:

Tulaga lelei:

2-mercaptomethylpyrazine e leai se lanu i le samasama tioata maʻa ma se manogi thiol uiga ese. E lelei le solubility i le vevela o le potu ma e solu i le vai, ava malosi ma ketone solvents.

Fa'aaogā:

2-mercaptomethylpyrazine o loʻo i ai le tele o faʻaoga. E masani ona faʻaaogaina e fai ma sui faʻaitiitiga i le faʻaogaina o meaola ma e mafai ona faʻaitiitia mea faʻapitoa e pei o ketones, aldehydes, acids ma alkyl halides. E fa'aaogaina fo'i i le fa'atupuina o mea fa'apipi'i ion u'amea, fa'amalosi mo le fa'aogaina o meaola, ma mea fa'alatalata mo nisi fungicides ma vaila'au fa'asaina.

Metotia:

O le auala autu o sauniuniga o le 2-mercaptomethylpyrazine e maua mai i le tali atu o le 2-bromomethylpyrazine ma le sodium sulfide (poʻo le ammonium sulfide). O laasaga fa'apitoa e fa'apea:

2-Bromomethylpyrazine e tali atu i le sodium sulfide (poʻo le ammonium sulfide) e maua ai le 2-mercaptopyrazine methane ma isi mea faʻatau.

O le faʻafefiloi o tali na faʻamamaina ma faʻamalama e maua ai le 2-mercaptomethylpyrazine.

Fa'amatalaga Saogalemu:

2-Mercaptomethylpyrazine o se faʻalapotopotoga faʻapitoa ma e tatau ona faʻaoga saogalemu. Atonu e i ai se aafiaga ita i mata, pa'u, ma le manava. Fai totigilima puipui ma matatioata pe a fa'aoga, ma fa'amautinoa se siosiomaga fa'alelei lelei. Pe a tagofia vailaʻau, mulimuli i faiga suʻesuʻe talafeagai e puipuia ai le paʻu ma mata ma aloese mai le manavaina o latou ausa. Pe a fa'afeso'ota'i po'o le manava, fufulu vave i le tele o vai ma saili fesoasoani fa'afoma'i.
