Pyridine-4-boronic acid（CAS# 1692-15-5) hoʻolauna
ʻO 4-Pyridine boronic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 4-pyridine boronic acid:
ʻAno maikaʻi:
- Ke ʻano: 4-pyridine boronic acid he paʻa kala kala ʻole.
- Hiki ke hoʻoheheʻe ʻia: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe kūlohelohe maʻamau e like me nā waiʻona, ethers, a me nā ketones.
- Paʻa: Paʻa ka 4-Pyridine boronic acid ma ka lumi wela, akā hiki ke hoʻoheheʻe ʻia ma ke alo o nā wela kiʻekiʻe, nā paʻi kiʻekiʻe, a i ʻole nā mea hoʻomake ikaika.
E hoʻohana:
- Catalyst: Hiki ke hoʻohana ʻia ka 4-pyridylboronic acid ma ke ʻano he catalyst i nā hopena synthesis organik, e like me ka hoʻokumu ʻana o ka paʻa CC a me nā hopena oxidation.
- Coordination reagent: Loaʻa iā ia nā ʻātoma boron, a hiki ke hoʻohana ʻia ka 4-pyridylboronic acid ma ke ʻano he coordination reagent no nā ion metala, e pāʻani ana i kahi kuleana nui i ka catalysis a me nā hopena kemika ʻē aʻe.
Hanana:
- Hiki ke loaʻa ka 4-Pyridine boronic acid ma ka hoʻopili ʻana i ka 4-pyridone me ka waikawa boric. E hoʻoponopono ʻia nā kūlana hoʻohālikelike kikoʻī e like me ke kūlana maoli.
ʻIke palekana:
- ʻO ka 4-Pyridine boronic acid he hui kūlohelohe maʻamau, akā pono nō e mālama pono i ka mālama ʻana. Pono e hoʻohana ʻia nā aniani pale a me nā mīkina lima no ka hana.
- Hōʻalo i ka pili ʻana me ka ʻili a me ka inhalation o ka lepo. Inā pili ʻole ka ʻili, holoi koke me ka wai nui.
- I ka hoʻohana ʻana a me ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants ikaika a me nā ʻakika ikaika e pale aku i ka hoʻoulu ʻana i nā hopena pōʻino.
- I ka wā e hoʻolei ai i ka ʻōpala, pono e hoʻolei ʻia me ka palekana e like me nā kānāwai kūloko.
