1-Bromo-2-fluoro-5-(trifluoromethoxy)benzene（CAS# 286932-57-8)

Hoʻolauna

ʻO ka 2-bromo-1-fluoro-4-(trifluoromethoxy)benzene he mea hoʻohuihui kino me ke ʻano kemika C7H3BrF4O.

ʻAno:

ʻO 2-bromo-1-fluoro-4-(trifluoromethoxy)benzene he wai waihoʻoluʻu ʻole a melemele iki me ka ʻala ʻala. He 1.834g/cm³ kona mānoanoa, kahi paila o 156-157 ° C, a me kahi kiko uila o 62 ° C. Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethanol, dimethylformamide a me dichloromethane.

E hoʻohana:

Hoʻohana nui ʻia ka 2-bromo-1-fluoro-4-(trifluoromethoxy) benzene ma ke ʻano he reagent i nā hopena synthesis organik. Hiki iā ia ke hoʻokomo i ka fluorine a me ka bromine atoms i ka synthesis o nā mea ʻala, a hoʻohana ʻia i ka hoʻomākaukau ʻana i nā lāʻau lapaʻau a me nā intermediates pesticide.

Hanana:

Hana ʻia ka hoʻomākaukau ʻana o 2-bromo-1-fluoro-4-(trifluoromethoxy) benzene e nā ʻano hana synthesis. ʻO kahi ʻano hana maʻamau o ka hoʻomākaukau ʻana ʻo ia ka hopena o 2-fluoro-5-(trifluoromethoxybenzene) me ka bromine ma lalo o nā kūlana acidic.

ʻIke palekana:

ʻO 2-bromo-1-fluoro-4-(trifluoromethoxy)benzene paha he mea ʻawaʻawa a hoʻonāukiuki i nā kānaka. I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono e lawe i nā mea e pono ai ka mālama ʻana a me ka palekana, e like me ke komo ʻana i nā mea pale kūpono (e like me nā mīkina lima a me nā maka aniani), e pale aku i ka hoʻopili ʻana me ka ʻili a me nā maka, a mālama i nā kūlana ventila maikaʻi. I ka lawelawe ʻana i kēia pūhui, e hahai i nā kaʻina hana palekana kūpono a e hahai pono i nā ʻōlelo aʻoaʻo ma ka pepa ʻikepili palekana.
