Hoʻolauna
ʻO 2-bromo-4-methylpyridine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
ʻO ka 2-Bromo-4-methylpyridine he wai kala ʻole a melemele me ka ʻala ʻala ikaika. Hiki ke ho'ohehe'e 'ia i loko o ka wai. He hui ia me ka haʻahaʻa o ka ʻona.
E hoʻohana:
Hoʻohana pinepine ʻia ʻo 2-Bromo-4-methylpyridine i nā hopena synthesis organik ma ke ʻano he koʻikoʻi koʻikoʻi. Loaʻa iā ia kahi ākea o nā noi i ka synthesis o nā pūhui heterocyclic a me nā moleke hana.
Hanana:
ʻO ka hapa nui o nā ʻano hoʻomākaukau o ka 2-bromo-4-methylpyridine ka hopena o ka chloride me ka potassium bromide a i ʻole ka bromic acid, a loaʻa ka huahana ma ke ʻano hoʻololi.
ʻIke palekana: Pono e hoʻohana ʻia nā mea pale kūpono e like me nā mīkina lima, nā maka maka maka maka i ka wā e hoʻohana ai. I ka mālama ʻana a me ka mālama ʻana, pono e pale ʻia ka hoʻopili ʻana me nā oxidants a me nā waikawa ikaika. Pono e hoʻokaʻawale ʻia mai nā lapalapa ākea a me nā kumu hoʻā. He palekana ka 2-Bromo-4-methylpyridine ke hoʻohana a mālama pono ʻia.
