Hoʻolauna
ʻO ka 2-bromo-3-chroo-5-(trifluoromethyl)pyridine he mea hoʻohuihui me ke ʻano C6H2BrClF3N. He wai waihoʻoluʻu ʻole a ʻeleʻele melemele me ke ʻala ʻala i ka wela lumi.
He nui ka hoʻohana ʻana o kēia pūhui ma ke kahua o ke kemika. Hiki ke hoʻohana ʻia ma ke ʻano he pesticide intermediate no ka hana ʻana i nā kemika mahiʻai e like me nā insecticides, fungicides a me nā herbicides. Eia kekahi, hiki ke hoʻohana ʻia i nā hopena synthesis organik ma ke ʻano he mea waiwai nui.
ʻO ka 2-bromo-3-chloro-5-(trifluoromethyl) pyridine ka mea maʻamau i hana ʻia e ka synthesis kemika. Aia kekahi ala kiko'ī e hoʻopili i ka 3-chloro-5-(trifluoromethyl) pyridine me ka lithium bromide i loko o ka ethanol e loaʻa ai ka huahana i makemake ʻia.
Ma keʻano o ka palekana, he mea hoʻonāukiuki a me ka corrosive kēia hui. I ka wā o ka lawelawe ʻana, pono e lawe ʻia nā hana palekana kūpono, e like me ke komo ʻana i nā mīkina lima pale a me nā goggles, e hōʻoia i ka hana ʻana o ka hana i loko o kahi ea maikaʻi. I ka manawa like, e pale i ka pili ʻana me ka ʻili, nā maka a me ka ʻōpū hanu. I ka mālama ʻana a me ka mālama ʻana, e mālama pono ʻia nā kaʻina hana palekana.
