ʻO 2-Fluoro-3-chloro-5-bromopyridine he mea hoʻohuihui.
He paʻa ka hui me ke ʻano keʻokeʻo a ʻulaʻula melemele. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela, akā hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka methanol a me ka methylene chloride.
Loaʻa i ka 3-Bromo-5-chloro-6-fluoropyridine kekahi waiwai noi i ka synthesis organik. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he waena no nā ʻano like ʻole i ka synthesis organik, e like me ka hoʻohui ʻana a me nā hopena hoʻohana hydrocarbon aromatic. Hiki i kēia mau hopena ke pāʻani i kahi hana koʻikoʻi i ke kūkulu ʻana i nā ʻano molekole organik paʻakikī.
Hiki ke hana ʻia ke ʻano o ka hoʻomākaukau ʻana i ka 3-bromo-5-chloro-6-fluoropyridine ma o nā ala like ʻole. ʻO ke ʻano maʻamau, ʻo ia ka hoʻokō ʻana i ka hopena halogenation stepwise ma o nā mea pani like o pyridine, e hoʻokomo mua i ka fluorine ma ke kūlana 3, a laila ka chlorine ma ke kūlana 5, a me ka bromine ma ke kūlana 6.
ʻIke palekana: 3-Bromo-5-chloro-6-fluoropyridine he kemika a pono e mālama ʻia e like me nā kaʻina hana palekana kūpono. Hiki ke hoʻonāukiuki i ka ʻili, nā maka, a me ka ʻōpū hanu, a pono e hoʻohana ʻia nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me nā lole pale i ka wā e hana ai.
Pono e hoʻokō ʻia ka mālama ʻana a me ka mālama ʻana i nā kemika e like me nā lula pili, a hoʻopaʻa ʻia a hoʻopaʻa inoa ʻia e like me nā waiwai kino o nā kemika. I ka hoʻohana ʻana, e hōʻoia i ka ea kūpono a pale i ka hoʻohu ʻana i nā kinoea a i ʻole nāhu.
