Intangiriro

2-Methylthio-3-methylpyrazine ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gutegura namakuru yumutekano:

Ubwiza:

1. Kugaragara: 2-methylthio-3-methylpyrazine mubisanzwe ni umweru ukomeye cyangwa kristaline, kandi birashobora no kuba muburyo bwifu.

2. Gukemura: Irashobora gushonga mumashanyarazi menshi nka chloroform, benzene, na Ethanol.

Koresha:

Uburyo:

2-Methylthio-3-methylpyrazine irashobora guhuzwa nintambwe zikurikira:

1. Hindura methyl thiocyanate na acetone mugihe gikwiye kugirango habeho heterocycle ya Kawasaki.

Noneho, heterocycle ya Kawasaki isubizwa hamwe na acide formique kugirango itange 2-methylthio-3-methylpyrazine.

Amakuru yumutekano:

1. 2-Methylthio-3-methylpyrazine igira ingaruka mbi kandi igomba kwirinda guhura nuruhu n'amaso.

2. Ibikoresho bikwiye birinda nka gants na gogles bigomba kwambarwa mugihe ukoresheje cyangwa ukora.

3. Niba ushizemo umwuka cyangwa winjiye, shaka ubuvuzi bwihuse.
