Hoʻolauna
ʻO 2,5-Dibromo-3-nitropyridine (2,5-dibromo-3-nitropyridine) he mea hoʻohuihui. ʻO kekahi o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o 2,5-dibromo-3-nitropyridine i hāʻawi ʻia ma lalo nei:
Nā waiwai:
- Nānā: 2,5-Dibromo-3-nitropyridine he paʻa melemele.
- Solubility: 2,5-Dibromo-3-nitropyridine hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, dimethyl sulfoxide a me dichloromethane a hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
Hoʻohana:
- Hoʻohana ʻia ka 2,5-Dibromo-3-nitropyridine ma ke ʻano he waena i ka synthesis organik.
- Hoʻohana ʻia ia i ka hoʻomākaukau ʻana i nā pūhui heterocyclic me ka nitrogen, e like me nā derivatives pyridine.
Ke ʻano o ka hoʻomākaukau ʻana:
- Hoʻomākaukau ʻia ka 2,5-dibromo-3-nitropyridine e hana pinepine ʻia e nā hopena synthetic. ʻO kahi ala synthetic maʻamau ka loaʻa ʻana o ka huahana i manaʻo ʻia mai pyridine ma ke ʻano he mea hoʻomaka e ka bromination a me ka nitration. Hiki ke hoʻololi ʻia nā ʻanuʻu synthetic kūpono e like me ka mea e pono ai.
ʻIke palekana:
- 2,5-Dibromo-3-nitropyridine ʻaʻohe pilikia palekana koʻikoʻi ma lalo o nā kūlana maʻamau o ka hoʻohana.
- Eia naʻe, ma ke ʻano he kemika, pono e mālama ʻia nā hana palekana maʻamau. Pono e ʻalo ʻia ka pili ʻana me ka ʻili, nā maka a me nā mucous membrane. Pono e ʻike ʻia nā hana pale pilikino e like me nā mīkina lima, nā maka aniani a me ka ʻaʻahu hale hana i ka wā e lawelawe ai.
- I ka hihia o ka ʻai ʻana a i ʻole ka inhalation o ka hui, e ʻimi koke i ka lāʻau lapaʻau. Inā pili ka ʻili a i ʻole ka maka, holoi koke me ka wai nui a ʻimi i ke kōkua olakino.
