Hoʻolauna

ʻO ka Methyl 3-bromo-6-chloropyrazine-2-carboxylic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna pōkole i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

ʻAno maikaʻi:
- Ke ʻano: ʻeleʻele a i ʻole melemele māmā paʻa
- Solubility: hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ether a me ka chloroform.

E hoʻohana:
- Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka no nā hopena synthesis organik, e like me ka synthesis o leucine a me ke aʻo ʻana i nā pūhui heterocyclic me ka nitrogen.

Hanana:
- ʻO ke ʻano o ka hoʻomākaukau ʻana o ka methyl 3-bromo-6-chloropyrazine-2-carboxylic acid ka hopena o ka 3-bromo-6-chloropyrazine me ka formic acid a me ka acid catalyst e hoʻopuka i ka huahana i manaʻo ʻia.

ʻIke palekana:
- Hiki ke hoʻonāukiuki i ka maka a me ka ʻili. Pono e hoʻohana ʻia nā lako pale pilikino e like me nā maka pale a me nā mīkina lima i ka wā e hoʻohana ai.
- Pono e mālama ʻia ma kahi maloʻo a maʻalili, ma kahi mamao o ke ahi a me nā mea hoʻoheheʻe.
- Pono e mālama ʻia nā lula palekana kūloko a me nā alakaʻi hana no ka hoʻohana pono ʻana a me ka mālama ʻana i kēia pūhui.
