Hoʻolauna
ʻO 2-Methylthiopyrazine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2-methylthiopyrazine:
ʻAno maikaʻi:
- ʻO 2-Methylthiopyrazine kahi kala ʻole i ke aniani melemele māmā a i ʻole ka pauka crystalline me kahi ʻala sulfur nāwaliwali.
- He alkaline ke hoʻoheheʻe ʻia i loko o ka wai a hiki ke hoʻoheheʻe ʻia i loko o nā hopena ʻawaʻawa a me ka alkaline.
- Ke wela a hoʻā ʻia paha, hoʻokuʻu ka 2-methylthiopyrazine i nā kinoea ʻawaʻawa.
E hoʻohana:
- Hoʻohana nui ʻia ka 2-Methylthiopyrazine i ka synthesis kemika ma ke ʻano he catalyst a i ʻole ligand no nā hopena synthesis organik.
Hanana:
- Loaʻa pinepine ʻia ka hoʻomākaukau ʻana o 2-methylthiopyrazine e ka hopena o ka sulfide me 2-chloropyridine. ʻO ka hana kikoʻī e hana i ka 2-chloropyridine me ka sodium sulfide i loko o kahi mea hoʻoheheʻe organik e loaʻa ai ka huahana o 2-methylthiopyrazine.
ʻIke palekana:
- ʻO 2-Methylthiopyrazine kahi mea ʻawaʻawa a pono e pale ʻia mai ka inhalation, ingestion, a i ʻole pili me ka ʻili a me nā maka.
- Pono e ʻaʻahu ʻia nā lako pale pilikino e like me nā mīkina lima, nā maka aniani, a me nā ʻaʻahu i ka wā e hoʻohana ai a hoʻomākaukau paha.
- Pono e hoʻohana ʻia i loko o kahi wahi e hoʻoheheʻe maikaʻi ʻia e pale aku i kāna ʻike mahu ma mua o ka palena palekana.
- I ka wā e mālama ai, pono e hoʻopaʻa paʻa ʻia, mai ke ahi a me nā mea ʻona.
- Inā loaʻa ka pilikia a i ʻole ka ʻai ʻana, e ʻimi koke i ka lāʻau lapaʻau.
