Hoʻolauna
ʻO ka 2,3-dibromo-5-methylpyridine (2,3-dibromo-5-methylpyridine) he mea hoʻohuihui kino me ke ʻano kemika C6H5Br2N. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
ʻO 2,3-dibromo-5-methylpyridine kahi paʻa melemele me kahi ʻala ʻala. He 63-65 degere Celsius kona wahi hehee a he 269-271 degere Celsius kona. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik.
E hoʻohana:
ʻO 2,3-dibromo-5-methylpyridine kahi mea hoʻohuihui kūlohelohe kūlohelohe. Hiki ke hoʻohana ʻia e synthesize i nā pūhui organik ʻē aʻe, e like me nā derivatives o nā mea biologically active, nā lāʻau lapaʻau a me nā pesticides. Hiki ke hoʻohana ʻia no ka synthesis waiwai o nā mea uila e like me nā organik light-emitting diodes (OLED) a me nā ʻōhua organik.
Hanana:
Hiki ke loaʻa ka 2,3-dibromo-5-methylpyrridine ma ka hana ʻana i ka 5-methylpyridine me ka bromine. Hoʻopili mua ʻo 5-Methylpyridine me ka hydrogen bromide, a laila hoʻomau i ka hana ʻana me ka methyl chloride i mua o kahi catalyst e hana i ka huahana i manaʻo ʻia.
ʻIke palekana:
ʻO 2,3-dibromo-5-methylpyrridine ka mea hoʻonāukiuki a hiki ke hoʻonāukiuki i ka maka, ka ʻili a me ka ʻōnaehana hanu. I ka wā o ka hoʻohana ʻana, pono e mālama pono ʻia nā kaʻina hana palekana, pono e pale ʻia ka pili pono ʻana me ka ʻili a me nā maka, a pono e hōʻoia ʻia ka hana ma kahi wahi i hoʻoluʻu maikaʻi ʻia. I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants a me nā mea puhi ahi e pale ai i ka hopena o ke ahi a me ka pahū. Inā inhaled a ʻike ʻia paha i kēia pūhui, e ʻimi koke i ka ʻōlelo aʻoaʻo a e nīnau i ke kauka ʻoihana.
