Hoʻolauna
ʻO ka 2,4-Dibromopyridine kahi hui kūlohelohe. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: 2,4-dibromopyridine he kala ʻole a i ʻole ka māmā melemele crystalline paʻa.
- Solubility: 2,4-dibromopyridine hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik e like me ka ethanol, dimethyl sulfoxide a me ka chloroform.
E hoʻohana:
- Nā Pelu: He mea hoʻohana maʻamau ia e hiki ke hoʻohana ʻia no ka hana ʻana i nā kala me nā kala like ʻole.
Hanana:
Hiki ke hoʻomākaukau ʻia ka 2,4-Dibromopyridine e kēia mau ʻano:
- Catalyst bromination: Ma lalo o nā kūlana alkaline, hiki ke loaʻa ka 2,4-dibromopyridine ma ka hana ʻana i ka pyridine me ka brominating agent.
- Carbon-deuterium chiral halogenation reaction: Loaʻa ka 2,4-dibromopyridine ma ka hana ʻana i ka substrate me ka bromine.
ʻIke palekana:
Pono e mālama ʻia ka palekana a me ka hoʻohana ʻana o 2,4-dibromopyridine e like me nā ʻōlelo aʻe:
- He mea ʻawaʻawa kēia pūhui a pono e mālama pono ʻia.
- Pono e ʻaʻahu ʻia nā mea pale ponoʻī e like me nā mīkina lima, nā maka aniani, a me nā lole pale i ka wā e lawelawe ai a hoʻohana.
- E hōʻalo i ka hanu ʻana i kona lepo a i ʻole e pili ana i ka ʻili a me nā maka.
- Pono e hoʻohana ʻia ma kahi e hoʻoheheʻe maikaʻi ʻia a pale i ka hoʻopili ʻana me kahi kumu ahi e pale ai i ke ahi a pahū paha.
- Pono e mālama ʻia nā kaʻina hana palekana i ka wā o ka mālama ʻana a me ka mālama ʻana.
