Hoʻolauna
ʻO 3,4-Dibromopyridine (CAS # 13534-90-2) he mea hoʻohui kino me ke ʻano kemika C5H3Br2N. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:
ʻAno:
ʻO 3,4-Dibromopyridine he paʻa ʻole a ʻeleʻele melemele me kahi ʻala ʻala ʻokoʻa. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol, chloroform a me dimethylformamide i ka mahana maʻamau. Hōʻike ia i kahi kiʻekiʻe o ka heheʻe a me ka paila.
E hoʻohana:
Loaʻa i ka 3,4-Dibromopyridine nā noi nui i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he catalyst a i ʻole reaction intermediate no ke komo ʻana i nā ʻano ʻano kūlohelohe like ʻole, e like me Suzuki coupling reaction, C-C bond formation reaction, etc. nā hui polimer.
Kaʻina hoʻomākaukau:
He mea maʻalahi ke ʻano o ka hoʻomākaukau ʻana o 3,4-dibromopyridine. ʻO kahi ala maʻamau ka hana ʻana i ka pyridine me ka bromine ma lalo o nā kūlana hopena kūpono e hana ai i ka 3,4-dibromopyridine. Hiki ke hoʻokō ʻia ka hopena ma ka mahana maʻamau a i ʻole ma lalo o ka wela.
ʻIke palekana:
Pono ka nānā palekana i ka wā e lawelawe ai i ka 3,4-dibromopyridine. Hiki iā ia ke hoʻonāukiuki a pōʻino paha i ka maka, ka ʻili, a me ka ʻōnaehana hanu. No laila, pono e hoʻohana ʻia nā mea pale kūpono e like me nā aniani palekana, nā mīkina lima a me nā lole pale i ka wā o ka hana. E hōʻalo i ka hoʻohu ʻana i kona mahu, a ʻoi aku ka maikaʻi o ka hana ʻana ma kahi wahi me ka makani. I ka wā e hoʻolei ai i ka ʻōpala, e nānā i nā lula kūloko a e hoʻolei pono iā ia. Inā loaʻa iā ʻoe kekahi pilikia olakino a palekana paha, pono ʻoe e huli koke i kahi ʻoihana.
