Hoʻolauna
ʻO ka Methyl-5-chloropyrazine-2-carboxylate he mea hoʻohuihui kino me ke kumu kemika C7H5ClN2O2. Eia ka wehewehe kikoʻī o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Nani: ʻO ka Methyl-5-chloropyrazine-2-carboxylate i ke ʻano o nā keʻokeʻo keʻokeʻo a i ʻole ka pauka crystalline.
-Ka helu heheʻe: ma kahi o 54-57 ℃.
-Pila paila: Ma kahi o 253-254 ℃.
-Solubility: Methyl-5-chloropyrazine-2-carboxylate hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe kūlohelohe, e like me ka ethanol a me ka dichloromethane.
-Stability: Paʻa ka hui ma lalo o nā kūlana mālama maʻamau.
E hoʻohana:
Loaʻa i ka Methyl-5-chloropyrazine-2-carboxylate kekahi waiwai hoʻohana i ka synthesis kemika a me ka māla lāʻau.
-Hōʻano kemika: Hiki ke hoʻohana ʻia e like me nā mea maka a i ʻole nā mea waena i ka synthesis organik no ka synthesis o nā mea hoʻohui ʻē aʻe, e like me nā pesticides, dyes a me nā intermediates pharmaceutical.
-Pharmaceutical field: Methyl-5-chloropyrazine-2-carboxylate e hana ma ke ʻano he waena i ka synthesis o kekahi mau lāʻau lapaʻau a loaʻa nā hana biological e like me antibacterial, sedative a me anti-inflammatory.
Hanana:
Hiki ke hoʻomākaukau ʻia ka Methyl-5-chloropyrazine-2-carboxylate e nā ʻanuʻu aʻe:
1. E hana i ka 5-chloropyrazine me ka Formic Anhydride e hana i ka 5-chloropyrazine -2-Formic Anhydride.
2. E hoʻololi i ka 5-chloropyrazine-2-carboxylic anhydride me ka methanol e hoʻopuka i ka huahana i manaʻo ʻia ʻo Methyl-5-chloropyrazine-2-carboxylate.
He ala maʻalahi kēia, akā ʻokoʻa ke ʻano hana synthesis e like me nā pono noiʻi like ʻole.
ʻIke palekana:
- ʻOi aku ka palekana o ka Methyl-5-chloropyrazine-2-carboxylate ma lalo o ka hana pololei, akā pono e mālama pono ʻia kēia mau mea palekana:
-Contact: Hōʻalo i ka pili pololei me ka ʻili a me nā maka. E hoʻohana i nā mea pale pilikino e like me nā mīkina lima lima a me nā maka aniani ke hana.
-Inhalation: Pono e hoʻolako ʻia kahi ʻōnaehana ea maikaʻi i ka wā o ka hana e hōʻoia i ka holo ʻana o ka ea i loko. Hōʻalo i ka hanu ʻana i ka lepo a i ʻole ka mahu.
-edible: Methyl-5-chloropyrazine-2-carboxylate no nā kemika, ua pāpā loa ʻia.
-Hoʻopaʻa: E mālama i ka mea hoʻohui i kahi maloʻo, ʻoluʻolu a me ka ea, ma kahi mamao o ke ahi a me nā mea puhi.
E ʻoluʻolu e hoʻomaopopo ʻoe no ka ʻike wale nō ka ʻike ma luna nei, a pono ʻoe e makaʻala a hahai i nā lula palekana o ka lab i ka wā e hoʻohana ai i kēia pūhui.
