Hoʻolauna
Ke hoʻolauna nei i ka mea hou loa i kā mākou hōʻiliʻili kemika, 2-Fluoro-4-bromobenzonitrile, kahi huahana kiʻekiʻe me ka helu CAS o 105942-08-3.
ʻO 2-Fluoro-4-bromobenzonitrile, i ʻike ʻia ʻo 4-bromo-2-fluorobenzonitrile, he kikowaena synthetic i hoʻohana nui ʻia no ka noiʻi a me nā kumu lapaʻau. He paʻa kala ʻole ia me kahi pae hoʻoheheʻe o 91-95°C, kahi e hiki ai ke hoʻoheheʻe ʻia i nā solvents organik e like me dichloromethane a me ka ethyl acetate.
Hanaʻia kā mākou huahana me ka hoʻohanaʻana i kaʻenehana hou a me nā mea hana hou, e hōʻoiaʻiʻo ana i kahi kiʻekiʻe o ka maʻemaʻe a me ka maikaʻi. Loaʻa i kā mākou 2-Fluoro-4-bromobenzonitrile ka pae maʻemaʻe o 99%, e kūpono ana ia no ka nui o nā noi.
ʻO kekahi o nā noi nui o kēia kemika i loko o ka palladium-catalyzed coupling reactions. He ʻāpana koʻikoʻi ia i ka synthesis o nā pūhui organik, e like me ka carbamates, phenols, a me nā pyrroles. ʻO nā mea hoʻohana ʻē aʻe o 2-Fluoro-4-bromobenzonitrile ka hoʻomākaukau ʻana i nā intermediates pharmaceutical, agrochemical, a me nā mea hoʻonaninani.
Ma kā mākou hale hana, hoʻomaka mua mākou i ka maikaʻi a me ka palekana, no laila ua hoʻopiha ʻia kā mākou huahana i loko o ka ʻeke kiʻekiʻe e hōʻoia i ka mālama ʻole ʻia mai ka haumia a palekana no ka lawe ʻana a me ka mālama ʻana. ʻO kā mākou hui o nā limahana e hōʻoia i kēlā me kēia huahana e hele i nā ana hoʻomalu maikaʻi ma mua o ka hoʻouna ʻia ʻana no ka hoʻouna ʻana.
I ka hopena, ʻo kā mākou 2-Fluoro-4-bromobenzonitrile he mea koʻikoʻi koʻikoʻi waena i hoʻohana ʻia i nā ʻoihana he nui, me nā lāʻau lapaʻau a me nā agrochemical. Me kā mākou huahana hoʻomaʻemaʻe kiʻekiʻe, hiki iā ʻoe ke hōʻoia i ka maikaʻi kiʻekiʻe a me ka maikaʻi o ka hoʻohana ʻana. E hoʻokaʻaʻike mai iā mākou i kēia lā e kau i kāu kauoha a hoʻohana i kā mākou kumukūʻai hoʻokūkū a me ka lawe wikiwiki.
