ʻO ka 2,5-Difluorobromobenzene kahi hui kūlohelohe. ʻO kēia ka hōʻike kikoʻī i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻO 2,5-Difluorobromobenzene he wai kala ʻole me kahi ʻala ʻokoʻa. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā waiʻona, eter, a me nā ketones.

 

E hoʻohana:

Hoʻohana pinepine ʻia ʻo 2,5-Difluorobromobenzene ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he ligand no nā organometallic catalysts a hoʻohana ʻia i nā hopena hoʻololi, hoʻohui pū ʻana, etc.

 

Hanana:

He paʻakikī ke ʻano o ka hoʻomākaukau ʻana o 2,5-difluorobromobenzene a hiki ke hoʻohui pinepine ʻia e kēia mau hopena:

Ma ke alo o ka bromobenzene, ka bromide cuprous a me ka difluoromethanesulfonamide e hoʻopili ʻia i mua o ka bromobenzene e hana i ka 2,5-difluorobromobenzene.

Hoʻopili ʻia ka Phenylmagnesium bromide me ka fluoride cuprous e hoʻohua i ka 2,5-diphenyldifluoroethane, a laila hoʻokau ʻia i ka bromination a me nā hopena iodination e loaʻa ai ka 2,5-difluorobromobenzene.

 

ʻIke palekana:

ʻO 2,5-Difluorobromobenzene he mea hoʻonāukiuki a hiki ke hōʻeha i ka pilikia ma o ka inhalation, kaʻili o kaʻili, a iʻole ka maka. Pono e pale ʻia ka ʻike pololei ʻana i ka ʻili a me nā maka i ka wā e pili ana, a pono e hoʻohana ʻia nā mea pale pilikino e like me nā mīkina lima a me nā maka aniani inā pono. I ka hoʻomākaukau ʻana a me ka hoʻohana ʻana, pono e uku ʻia ka nānā ʻana i ke ahi a me ka pahū ʻana, a e hōʻoia i nā kūlana ventilation maikaʻi. I ka hoʻohana ʻana a me ka mālama ʻana, pono e mālama ʻia ka 2,5-difluorobromobenzene i kahi mahana kūpono a i loko o kahi pahu i hoʻopaʻa ʻia, mai ka ʻāʻī ʻana, ka wela a me nā oxidants.
