Hoʻolauna
ʻO 2-Chloro-3-amino-5-bromopyridine kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna pōkole i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Nā hiʻohiʻona: Keʻokeʻo a ʻeleʻele melemele keokeo
- Hiki ke hoʻoheheʻe: Hiki ke hoʻoheheʻe ʻia i ka chloroform a me ka ethanol, hiki ke hoʻoheheʻe iki i ka wai
E hoʻohana:
- Hiki ke hoʻohana ʻia ka pūhui ma ke ʻano he catalyst i ka synthesis organik a he hana koʻikoʻi i ka synthesis o nā pūhui organik ʻē aʻe.
Hanana:
- Hoʻohana pinepine ʻia ka synthesis o 2-chloro-3-amino-5-bromopyridine me ka hoʻohana ʻana i ka hopena chlorination-bromination. Hoʻomākaukau ʻia ia ma ka hana ʻana i ka 3-amino-4-bromopyridine me nā mea chlorinating (e like me ka phosphorus trichloride, sulfuryl chloride, etc.).
ʻIke palekana:
- He kemika ka 2-Chloro-3-amino-5-bromopyridine a pono e mālama pono e like me ke komo ʻana i nā mīkina lima kemika a me nā maka.
- I ka hoʻohana ʻana a mālama ʻana, pono e ʻalo ʻia ka hoʻopili ʻana me nā oxidants, nā ʻakika ikaika, a me nā alkali ikaika e pale aku i nā hopena pōʻino.
- Hiki iā ia ke lilo i kemika i ʻoi aku ka paʻakikī i ka ʻili, nā maka, a me ka ʻōnaehana hanu, a pono e holoi ʻia me ka wai ma hope koke o ka hoʻopili ʻana me ia a pono e ʻimi ʻia ka lāʻau lapaʻau.
