Mawu Oyamba
5-Methyl-6,7-dihydro-5H-cyclopentapyrazine. Ndi mtundu woyera wa crystalline wolimba womwe umafanana ndi kristalo kapena ufa mu maonekedwe. Chinthucho chimakhala chokhazikika kutentha, koma pang'onopang'ono amawola pansi pa kutentha kwakukulu, kuwala kapena mpweya.
5-Methyl-6,7-dihydro-5H-cyclopentapyrazine ili ndi ntchito zambiri. Ndi mankhwala ophera tizilombo omwe amagwiritsidwa ntchito paulimi poletsa kukula ndi kubereka kwa tizirombo.
Pali njira ziwiri zazikulu zokonzekera 5-methyl-6,7-dihydro-5H-cyclopentapyrazine. Imodzi imapezedwa ndi condensation reaction ya N-methylpyrazine, ndiyeno hydrogenation reaction imachitika kuti apeze zomwe akufuna. Zina zimapangidwira ndi makutidwe ndi okosijeni ndi kuchepetsa zomwe 5-benzoyl-6,7-dihydro-5H-cyclopentapyrazine.
Chidziwitso cha Chitetezo: 5-Methyl-6,7-dihydro-5H-cyclopentapyrazine ndi poizoni. Zikhoza kukhala ndi zotsatira zokwiyitsa pamanjenje ndi kupuma kwa thupi ndipo zimakwiyitsa khungu ndi maso. Njira zoyenera zodzitetezera monga kuvala zodzitchinjiriza zamaso, magolovesi ndi zishango zakumaso zimafunikira panthawi yogwira ntchito. Zinthuzi ziyenera kusungidwa mu chidebe chotchinga mpweya, kutali ndi kuyatsa ndi okosijeni. Pogwiritsira ntchito mankhwalawa, fumbi ndi ma aerosols ziyenera kupewedwa, ndipo kupuma ndi kukhudzana ndi khungu kuyenera kupewedwa. Ngati akhudzidwa, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala. Pogwira ndikugwiritsa ntchito 5-methyl-6,7-dihydro-5H-cyclopentapyrazine, tsatirani mosamala ndondomeko zotetezera zoyenera.
