Hoʻolauna
ʻO ka 2,4-difluorobenzylbromide he mea hoʻohuihui mea ola me ke ʻano kemika C7H5BrF2. He wai waihoʻoluʻu me ka ʻala ikaika. Eia ka wehewehe ʻana o kekahi o nā waiwai, hoʻohana, nā ʻano a me nā ʻike palekana o 2,4-difluorobenzylbromide:
ʻAno:
-Nani: 2,4-difluorobenzylbromide he wai kala ʻole.
-Solubility: Hiki ke hoʻoheheʻe ʻia me nā solvents organik, e like me ka ethanol, chloroform a me dimethylformamide.
E hoʻohana:
Hiki ke hoʻohana ʻia -2,4-difluorobenzylbromide ma ke ʻano he intermediate i ka synthesis organik a hoʻohana ʻia i ka synthesis o nā pūhui ʻē aʻe.
-Hiki ke hoʻohana ʻia ma ke ʻano he mea maka ma ke kahua o nā pesticides a me nā lāʻau lapaʻau.
Hanana:
-2,4-difluorobenzylbromide ka mea maʻamau i hoʻomākaukau ʻia ma ka hana ʻana i ka 2,4-difluorobenzoic acid me ka bromine.
- Hiki i ke ala hoʻomākaukau kūikawā ke hoʻololi i nā kūlana hopena a me nā reagents i hoʻohana ʻia e like me ka mea e pono ai.
ʻIke palekana:
- ʻO 2,4-difluorobenzylbromide ka mea hoʻonāukiuki a pono e nānā i nā mea pale e like me ke komo ʻana i nā mīkina lima a me nā lole pale.
-E pale i ka inhalation, pili me ka ʻili a me nā maka i ka wā e hoʻohana ai.
-I ka hihia o ka inhalation ulia a i ʻole ka launa pū ʻana, pono e hoʻoneʻe koke ʻia ka mea i hoʻopilikia ʻia i kahi ea hou a mālama ʻia me ka mālama olakino.
-I ka mālama ʻana, e mālama i ka 2,4-difluorobenzylbromide mai ke ahi a me ka oxidant e pale aku i ka pilikia o ke ahi a me ka pahū.
