Hoʻolauna pōkole
ʻO ka 3-Bromo-5-nitro-2-hydroxypyridine kahi mea hoʻohui i hoʻopaʻa ʻia e like me BNHO.

Nā Waiwai: Nānā:
- Ke ʻano: ʻO BNHO he aniani melemele māmā a i ʻole ka pauka crystalline.
- Solubility: hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka waiʻona, ether a me nā mea hoʻoheheʻe organik ʻē aʻe.

Hoʻohana:
- Pesticide raw material: Hiki ke hoʻohana ʻia ʻo BNHO ma ke ʻano he mea maka no ka synthesis o kekahi mau pesticides.

Kaʻina hoʻomākaukau:
ʻElua mau ʻano hoʻomākaukau maʻamau: ʻo kekahi ma o ka alkylation reaction o bromobenzene a me 2-hydroxypyridine e loaʻa ai ka 3-bromo-2-hydroxypyridine, a laila e hana me ka nitric acid e loaʻa ai ka 3-bromo-5-nitro-2-hydroxypyridine. ʻO ka mea ʻē aʻe ma o ka hopena o 2-bromo-3-methylpyridine me ka waikawa nitric e loaʻa ai ka 3-bromo-5-nitro-2-hydroxypyridine.

ʻIke palekana:
- ʻO BNHO kahi hui organohalogen i ʻona a hoʻonāukiuki a pono e mālama ʻia nā hana pale.
- Hōʻalo i ka pili ʻana me ka ʻili, nā maka a me nā membrane mucous; inā pili, holoi koke me ka wai nui.
- E hoʻohana i nā lako pale pilikino kūpono, e like me nā mīkina lima lima a me nā aniani palekana, ke hoʻohana a hoʻomākaukau ʻia.
- Hōʻalo i ka hanu ʻana i ka mahu a i ʻole ka lepo a e hana ma kahi ea maikaʻi.
- Pono e mālama ʻia ma kahi maloʻo, ʻoluʻolu a hoʻoheheʻe ʻia ma kahi mamao mai nā kumu hoʻāla a i ʻole nā ​​​​mea hana oxidizing.
