Hoʻolauna

ʻO ka 2-Chloro-3,5-dibromopyridine he mea hoʻohuihui mea ola me ke ʻano kemika C5H2Br2ClN. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

 

ʻAno:

- ʻO 2-Chloro-3,5-dibromopyridine he mea paʻa, kala ʻole a ʻeleʻele melemele. He 61-63 degere Celsius kona wahi hehee a he 275-280 degere Celsius kona.

-He mea hoʻoheheʻe ikaika, hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik, e like me ka ethanol, dimethylformamide a me dichloromethane.

 

E hoʻohana:

- Hoʻohana nui ʻia ka 2-Chloro-3,5-dibromopyridine i nā hopena synthesis organik ma ke ʻano he koʻikoʻi koʻikoʻi. Hiki ke hoʻohana ʻia i ka synthesis o nā lāʻau lapaʻau hou, nā pesticides a me nā mea ʻē aʻe.

-Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻokaʻawale metala a me kahi precursor no nā mea optical.

 

Kaʻina hoʻomākaukau:

- Hiki ke hoʻomākaukau ʻia ka 2-Chloro-3,5-dibromopyridine ma ka hana ʻana i ka 3,5-dibromopyridine me kahi mea chlorinating. No ka laʻana, hiki ke hoʻokaʻawale ʻia ka dibromopyridine me ka hoʻohana ʻana i ka sulfoxide a me ka chlorine ma lalo o nā kūlana hopena kūpono e hāʻawi i ka huahana.

 

ʻIke palekana:

- 2-Chloro-3,5-dibromopyridine he mea ʻawaʻawa a pono e mālama ʻia e pale i ka inhalation, pili me ka ʻili a me ka ʻai ʻana. E hoʻohana i nā lako pale pilikino kūpono e like me nā mīkina lima pale, nā aniani a me nā maka ke hoʻohana.

-I ka mālama ʻana a me ka mālama ʻana i ka 2-Chloro-3,5-dibromopyridine, e hahai i nā kaʻina hana palekana e pili ana a hōʻoia i kahi kaʻina hana maikaʻi.

-Ina pili a inhalation paha, e imi koke i ka lapaau mai kahi i kumu mai.
