2,3-Dibromopyridine (CAS # 13534-89-9) hoʻolauna

ʻO ka 2,3-dibromopyridine kahi hui kūlohelohe. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana, a me ka ʻike palekana.
ʻano:
ʻO -2,3-dibromopyridine he paʻa ʻole a ʻeleʻele melemele me ka ʻala ʻala.
-He mea hoʻoheheʻe ia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol, dimethylformamide, a me dichloromethane ma ka lumi wela, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
- He mea maʻalahi kēia hui i ka mālamalama a me ka ea a pono e mālama ʻia i loko o kahi pahu i hoʻopaʻa ʻia mai ka mālamalama.
Ke kumu:
Hoʻohana pinepine ʻia ka -2,3-dibromopyridine ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik.
-Hiki ke hoʻohana ʻia no ka hoʻololi ʻana a me nā hopena condensation i ka synthesis organik.
ʻano hana hana:
-ʻO ke ala maʻamau no ka hoʻomākaukau ʻana i ka 2,3-dibromopyridine ma o ka hopena bromination o pyridine.
ʻO kahi ʻano hoʻomākaukau maʻamau e hoʻomaʻamaʻa i ka pyridine i ka wai bromine concentrated no ka pane ʻana, a ʻo ka hopena 2,3-dibromopyridine e hoʻoheheʻe ʻia mai ka hopena hopena ma hope o ka hoʻoilo.
ʻIke palekana:
ʻO -2,3-dibromopyridine he mea hoʻonāukiuki e hiki ai ke hoʻonāukiuki i ka maka a me ka ʻili i ka hoʻopili ʻana.
- Pono e hoʻohana ʻia nā mea pale pono e like me nā mīkina lima, nā maka aniani, a me nā lole pale i ka wā o ka hana.
-E hōʻalo i ka hanu ʻana i kona lepo a i ʻole ke kinoea, a e hana ma kahi wahi e hoʻoheheʻe maikaʻi ʻia.
