Ubwiza:
- Kugaragara: 2-ethyl-3-methylpyrazine iri mumazi atagira ibara cyangwa muburyo bwa kristaline.
- Gukemura: Ifite imbaraga nke mumazi, ariko irashobora gushonga mumashanyarazi.
- Guhagarara: Nibintu bihamye, ariko kwirinda kwirinda okiside ikomeye na acide zikomeye bigomba kwirindwa.
Koresha:
- 2-Ethyl-3-methylpyrazine ni reagent ikunze gukoreshwa kandi ikoreshwa no hagati muguhuza imiti.
Uburyo:
2-Ethyl-3-methylpyrazine irashobora gutegurwa nuburyo bukurikira:
- Ethyl bromide yabanje gukoreshwa na pyrazine kugirango itange 2-Ethylpyrazine mubihe bya alkaline.
- Nyuma, 2-Ethylpyrazine isubizwa hamwe na methyl bromide kugirango itange 2-Ethyl-3-methylpyrazine.
Amakuru yumutekano:
- 2-Ethyl-3-methylpyrazine muri rusange ifatwa nkuburozi buke, ariko hagomba gukurikizwa protocole yumutekano ikwiye.
- Irinde guhumeka, guhura nuruhu n'amaso, kandi wambare ibikoresho byokwirinda nka gants, indorerwamo, hamwe ningabo zo mumaso.
- Mugihe ubitse kandi ukabitunganya, irinde inkomoko yumuriro hamwe na okiside kugirango wirinde ibyago byumuriro no guturika.
- Reba ibitabo byumutekano bijyanye nimpapuro zumutekano zitangwa nuwabitanze kugirango amakuru arambuye kandi yuzuye.
