Hoʻolauna
ʻO ka 5-bromo-3-cyanopyridine ka mea hoʻohuihui mea ola me ke ʻano kemika C6H3BrN2. He aniani keʻokeʻo a melemele, hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka dimethyl sulfoxide. Eia ka wehewehe kikoʻī o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o 5-bromo-3-cyanopyridine:
ʻAno:
-Nani: Keʻokeʻo a ʻulaʻula melemele
-Ka helu hehee: ma kahi o 89-93°C
-Pila paila: ma kahi o 290-305°C
-Density: Ma kahi o 1.64 g/mL
-Molecular kaumaha: 174.01g/mol
E hoʻohana:
Hoʻohana pinepine ʻia ʻo 5-bromo-3-cyanopyridine ma ke ʻano he intermediate i ka synthesis organik, a he mau noi koʻikoʻi ma nā kahua o ka synthesis lāʻau lapaʻau, synthesis pesticide a me ka synthesis dye.
Loaʻa nā noi kikoʻī:
-Ma ke kahua o ka lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize i nā lāʻau anti-tumor, nā lāʻau antiviral a me nā lāʻau antibacterial.
-Ma ke kahua o nā pesticides, hiki ke hoʻohana ʻia no nā pesticides synthetic a me nā herbicides.
-Ma ke kahua o nā dyes, hiki ke hoʻohana ʻia e synthesize i nā mea hoʻonaninani.
Kaʻina hoʻomākaukau:
Hiki ke hana ʻia ke ʻano o ka hoʻomākaukau ʻana o 5-bromo-3-cyanopyridine e nā ʻanuʻu aʻe:
1. Hoʻopili ka 3-cyanopyridine me ka waika hydrobromic ma lalo o nā kūlana alkaline e hana i ka 5-bromo-3-cyanopyridine.
ʻIke palekana:
Pono e mālama ʻia kēia mau mea palekana i ka wā e hoʻohana ai i ka 5-bromo-3-cyanopyridine:
-He mea hoʻohuihui mea hoʻonanea ia. E hōʻalo i ka hanu ʻana i ka lepo a i ʻole e pili ana i ka ʻili a me nā maka.
-I ka hoʻohana ʻana a me ka mālama ʻana, pono e hahai i nā kaʻina hana palekana, e hoʻohana i nā mea pale pilikino, e like me nā mīkina lima a me nā aniani palekana.
-E hōʻalo i ka hui ʻana a i ʻole ka hoʻopili ʻana me nā mea e like me nā oxidants ikaika a me nā ʻakika ikaika e pale ai i nā hopena pōʻino.
- E mālama ma kahi e wehe ʻia mai nā lapalapa a me nā kumu wela.
-Inā inhaled a pili paha me ka ʻili a me nā maka, holoi koke me ka wai. E ʻimi i ke kōkua olakino inā pono.
I ka nānā ʻana i nā pilikia palekana, pono ka hoʻohana ʻana a me ka mālama ʻana i ka 5-bromo-3-cyanopyridine e hahai i nā kaʻina hana hoʻokolohua kūpono a hoʻokō i nā lula palekana kūpono.
