He pūhui olaola me ke kumu hoʻoheheʻe kemika C6H5BrFN. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana: Nature:
he wai waihoʻoluʻu a ʻeleʻele melemele. He ʻala ʻala ma ka lumi wela. ʻOi aku ke kiʻekiʻe o ka pūhui, a hoʻonui ʻia kona helu hoʻoheheʻe a me ka helu paila me ka piʻi ʻana o ka bromine maʻiʻo.

E hoʻohana:
Hoʻohana nui ʻia ia ma ke ʻano he reagent a i ʻole waena i ka synthesis organik. Hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā lāʻau lapaʻau, nā pesticides a me nā pūhui organik ʻē aʻe. Hiki ke hoʻohana ʻia ma ke ʻano he reagent i ka noiʻi a me nā laboratories.

Hanana:
ʻO ke ʻano o ka hoʻomākaukau ʻana i ka pill ka nui o ka hopena ʻelua. ʻO ka mua, hoʻopili ʻia ka bromomethylpyridine me ka fluoride potassium i loko o kahi mea hoʻoheheʻe organik e hoʻokomo i kahi atom fluorine. Hoʻopili ʻia ka pūhui bromofluoro i ka halogen e pili ana me ka hydrogen peroxide a i ʻole nā ​​​​mea hoʻoneʻe ʻē aʻe.

ʻIke palekana:
He mea hoʻohuihui ia a pono e mālama pono ʻia. I ka wā o ka hoʻohana ʻana a i ʻole ka hoʻomākaukau ʻana, pono e lawe ʻia nā hana palekana kūpono, e like me ke komo ʻana i nā mīkina lima pale kemika, nā maka aniani a me nā ʻōnaehana hoʻopau ma waho o ka hale hana. E pale i ka pili ʻana me ka ʻili a me nā maka, a pale i ke ahi. I ka mālama ʻana, e hoʻopaʻa ʻia ka pahu a waiho i kahi maloʻo a maloʻo. Inā ʻai ʻia a pili ʻili paha, e ʻimi koke i ka lāʻau lapaʻau.
