Hoʻolauna pōkole
ʻO 2-Bromopyridine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

ʻAno maikaʻi:
- 2-Bromopyridine he wai waihoʻoluʻu a melemele me kahi ʻono ʻono kūikawā.
- 2-Bromopyridine hiki ke hoʻoheheʻe iki ʻia i ka wai, akā ʻaʻole hiki ke hoʻoheheʻe ʻia a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka etera.

E hoʻohana:
- ʻO 2-Bromopyridine kahi reagent i hoʻohana nui ʻia i ke kahua o ka synthesis organik. Hoʻohana maʻamau ia e like me ka catalyst, ligand, intermediate, etc.

Hanana:
- Hiki ke hoʻomākaukau ʻia ka 2-Bromopyridine e nā ʻano kumu ʻelua:
1. Ma ka lumi wela, ua hoʻomākaukau ʻia ka bromine e ka hopena me ka pyridine.
2. Hoʻohana ʻia ka Ethyl bromoketone a me ka hopena pyridine e loaʻa ai ka 2-bromopyridine.

ʻIke palekana:
- ʻO 2-Bromopyridine kahi hui organohalogen me kekahi mea ʻona. ʻO ka ʻike ʻana a i ʻole ka inhalation o ia mea hiki ke hōʻeha i ke olakino kanaka.
- I ka wā e hoʻohana ai, e hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me nā lole pale.
- Pono e mālama ʻia mai nā mea puhi ahi a me nā kumu wela kiʻekiʻe a mālama ʻia i kahi wahi anuanu a maikaʻi.
- I ka wā e hoʻolei ai i ka ʻōpala, pono e hoʻolei ʻia e like me nā kānāwai kūloko a me nā lula e pale aku ai i ka haumia o ke kaiapuni.
- Ma mua o ka hoʻohana ʻana i ka 2-bromopyridine, e ʻoluʻolu e heluhelu a hahai i ka pepa ʻikepili palekana o ka huahana a me nā kuhikuhi hana kūpono.
