Hoʻolauna
ʻO 5-Bromo-2,3-diaminopyridine kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Keʻano: 5-Bromo-2,3-diaminopyridine keʻokeʻo i ka māmā melemele crystalline a iʻole ka pauka crystalline.
- Solubility: Hiki ke hoʻoheheʻe ʻia ka hui i loko o ka wai a maikaʻi ka solubility i nā mea hoʻoheheʻe organik.
E hoʻohana:
- Hoʻohana pinepine ʻia ka 5-Bromo-2,3-diaminopyridine ma ke ʻano he reagent i nā hopena synthesis organik.
- Hiki ke hoʻohana ʻia ma ke ʻano he waena i ka synthesis o nā pūhui coordination a i ʻole catalysts.
Hanana:
Hiki ke hoʻokō ʻia ka hoʻomākaukau ʻana o 5-bromo-2,3-diaminopyridine e nā pae aʻe:
1. E hoʻoheheʻe i ka 2,3-diaminopyridine i ka waika hydrochloric dilute mua.
2. Hoʻohui ʻia ka sodium nitrite e hana i nā pūhui nitroso.
3. Ma lalo o nā kūlana wai hau, hoʻohui ʻia ka potassium bromide e hana i ka 5-bromo-2,3-diaminopyridine.
ʻIke palekana:
- ʻO 5-Bromo-2,3-diaminopyridine he mea hoʻohuihui kūlohelohe pono e mālama ʻia a hoʻohana pono ʻia e pale aku i ka pili ʻana me ka ʻili a me nā maka.
- I ka wā e hana ai, pono e mālama ʻia nā hana palekana o ka hale hana, e like me ke komo ʻana i nā mea pale kūpono (e laʻa, nā mīkina lima, nā aniani, ka lole lab, etc.).
- E mālama i ka pūhui i mea e pale aku ai i nā pōʻino i hana ʻia e ka inhalation, ingestion, a i ʻole ka hoʻopili ʻana.
Ma ka noiʻi kemika a me nā hoʻokolohua, he mea nui e hana i kahi hana maikaʻi o ka mālama ʻana i ka palekana lab a hana e like me ke alakaʻi ʻana o ka poʻe loea.
