ʻO ka 3,5-Dibromo-2-fluoropyridine he mea hoʻohuihui kūlohelohe me ke ʻano kemika C5H2Br2FN. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:
ʻAno:
- ʻO 3,5-Dibromo-2-fluoropyridine kahi hui paʻa me kahi hiʻohiʻona keʻokeʻo keʻokeʻo.
-ʻO kona helu hoʻoheheʻe he 74-76 ℃, a ʻo kona wahi hoʻolapalapa he 238-240 ℃.
-ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela, akā hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe organik e like me ka ether a me ka ethanol.
E hoʻohana:
- ʻO 3,5-Dibromo-2-fluoropyridine he mea koʻikoʻi koʻikoʻi koʻikoʻi i hoʻohana nui ʻia i nā hopena synthesis organik.
-Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā mea photovoltaic organik, a hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā lāʻau lapaʻau, nā meaʻala a me nā pesticides.
Kaʻina hoʻomākaukau:
- Hiki ke hoʻomākaukau ʻia ka 3,5-Dibromo-2-fluoropyridine e ka hopena o ka pyridine iodide a me ka bromide cuprous.
-E hoʻoheheʻe mua i ka bromide cuprous a me ka pyridine iodide i ka dimethyl sulfoxide ma ka lumi wela e hana i ka reactant, a laila e hoʻohui mālie i ke kālā fluoride dropwise i ka haʻahaʻa haʻahaʻa, a me ka wela a hiki i ka pau ʻana o ka hopena.
ʻIke palekana:
- 3,5-Dibromo-2-fluoropyridine he mea hoʻonāukiuki i kaʻili a me nā maka, a pono e mālamaʻia nā hana palekana i ka wā e pili ana.
-E noʻonoʻo i ka ventila maikaʻi i ka wā e hoʻohana ai i kēia pūhui.
-ʻO ka decomposes i ke kiʻekiʻe wela e hoʻopuka i nā kinoea ʻino, a pono ia e pale aku i ka ʻike ʻana i nā lapalapa ahi a i ʻole nā wahi wela wela.
-E mālama iā ia ma kahi ʻano sila a pale i ka hoʻopili ʻana me nā oxidants a me nā ʻakika ikaika e pale aku i nā hopena pōʻino.
