Mawu Oyamba

2-Methoxy-3-isopropylpyrazine, yomwe imadziwikanso kuti MIBP (Methoxyisobutylpyrazine), ndi mankhwala achilengedwe. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

Ubwino:

- Maonekedwe: Madzi opanda mtundu

- Fungo: Limanunkhira ngati tsabola wobiriwira

Gwiritsani ntchito:

Njira:

2-Methoxy-3-isopropylpyrazine ikhoza kupangidwa ndi njira zotsatirazi:

Sodium sulphate ndi sodium bicarbonate amagwiritsidwa ntchito kusintha pH mtengo.

Pyrazine, isopropyl magnesium bromide, ndi methanol amachita pa kutentha koyenera.

Zomwezo zikamalizidwa, pawiri koyera ndi distilled ndi crystallized.

Zambiri Zachitetezo:

- 2-Methoxy-3-isopropylpyrazine ili ndi kawopsedwe kakang'ono koma imafunikirabe kuti mankhwalawa azitsatiridwa.

- Pewani kukhudza khungu, maso, ndi mucous nembanemba. Mukakhudza, muzimutsuka nthawi yomweyo ndi madzi ambiri.
