5-Methyl-6,7-dihydro-5H-cyclopentapyrazine. He paʻa keʻokeʻo keʻokeʻo e like me ke aniani a i ʻole ka pauka i ke ʻano. Paʻa ka mea ma ka lumi wela, akā e hoʻoheheʻe mālie ʻia ma lalo o ka hana o ka wela kiʻekiʻe, māmā a oxygen paha.
ʻO 5-Methyl-6,7-dihydro-5H-cyclopentapyrazine ka nui o nā noi. He insecticide maikaʻi ia i hoʻohana ʻia i ka mahiʻai e hoʻomalu i ka ulu a me ka hana hou ʻana o nā pests.
ʻElua mau ala nui e hoʻomākaukau ai i ka 5-methyl-6,7-dihydro-5H-cyclopentapirazine. Loaʻa kekahi ma ka condensation reaction o N-methylpyrazine, a laila lawe ʻia ka hopena hydrogenation no ka loaʻa ʻana o ka huahana i manaʻo ʻia. Hoʻopili ʻia ka mea ʻē aʻe e ka oxidation a me ka hoʻohaʻahaʻa ʻana o ka 5-benzoyl-6,7-dihydro-5H-cyclopentapirazine.
ʻIke palekana: 5-Methyl-6,7-dihydro-5H-cyclopentapyrazine he mea ʻawaʻawa. He hopena hoʻonāukiuki paha ia ma ke kino a me nā ʻōnaehana hanu a hoʻonāukiuki i ka ʻili a me nā maka. Pono nā hana pale pilikino e like me ke komo ʻana i nā maka maka, nā mīkina lima a me nā pale maka i ka wā o ka hana. Pono e mālama ʻia ka mea i loko o kahi pahu paʻa i ka ea, ma kahi mamao o ka ʻā a me nā mea oxidants. I ka lawelawe ʻana i ka mea waiwai, pono e pale ʻia ka lepo a me nā aerosol, a pale ʻia ka inhalation a me ka pili ʻana i ka ʻili. Inā loaʻa ka ʻike, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau. I ka lawelawe ʻana a me ka hoʻohana ʻana i ka 5-methyl-6,7-dihydro-5H-cyclopentapirazine, e hahai pono i nā kuʻina palekana kūpono.
