3,4-Difluoronitrobenzene: He mea waiwai no ka hana ʻana i nā lāʻau lapaʻau.
ʻO 3,4-Difluoronitrobenzene he mea waiwai nui i hoʻohana ʻia ma ke ʻano he precursor a i ʻole waena i ka hana ʻana i nā lāʻau lapaʻau. Ua ʻike ʻia kēia ʻano mea hoʻohana ma ke ʻano he fluoroaromatic, ʻo ia hoʻi, aia i loko o nā pūʻulu hana fluorine a me nā mea ʻala. ʻO nā pūhui Fluoroaromatic he mau mea kūkulu hale nui no ka hana ʻana i nā lāʻau lapaʻau, nā pesticides, a me nā mea kemika ʻē aʻe.
ʻO kekahi o nā noi koʻikoʻi o 3,4-difluoronitrobenzene ma ke ʻano he lāʻau lapaʻau ikaika (API) i ka hana ʻana i nā lāʻau lapaʻau like ʻole. Hoʻohana ʻia kēia pūhui i ka synthesis o kekahi mau lāʻau lapaʻau, e komo pū me nā antifungal agents, antibiotics, anticancer drugs, a me nā lāʻau anti-inflammatory. Hoʻohana pono nā mea pani fluoro i kēia pūhui no ka hoʻolālā ʻana i nā lāʻau lapaʻau i hiki ke hoʻopaʻa pono i nā pathogens a i ʻole kaʻina hana.
ʻO 3,4-Difluoronitrobenzene kekahi mau waiwai ʻē aʻe e lilo ia i mea hoʻohui maikaʻi no ka hana lāʻau lapaʻau. No ka laʻana, loaʻa i ka pūhui nā waiwai solubility maikaʻi loa, e hiki ai iā ia ke hoʻoheheʻe maʻalahi i nā ʻano mea hoʻoheheʻe a me nā reactants. Loaʻa iā ia ke kūpaʻa wela maikaʻi, ʻo ia hoʻi, hiki iā ia ke pale i nā wela kiʻekiʻe a me nā paʻi i ka wā o nā hopena kemika. Hoʻohui ʻia, maʻalahi kēia pūhui e synthesize a hoʻokaʻawale, kahi e lilo ai ia i kumu kūʻai kūpono no ka hoʻomohala ʻana i ka lāʻau.
ʻO ka hiʻohiʻona o 3,4-difluoronitrobenzene he wai melemele maʻemaʻe, kahi e maʻalahi ai ka lawelawe a me ka lawe ʻana. Hoʻopaʻa pinepine ʻia ka pūhui i loko o nā pahu airtight e pale ai i ka oxidation a me ka contamination. Pono e mālama ʻia mai ka wela a me ka lapalapa ʻana, no ka mea, hiki ke hoʻopau ʻia.
ʻO ka holoʻokoʻa, ʻo 3,4-difluoronitrobenzene kahi mea hoʻohana nui a versatile no ka hana lāʻau lapaʻau. ʻO kona mau waiwai a me nā hiʻohiʻona e lilo ia i mea waiwai nui no ka synthesis o nā lāʻau lapaʻau ākea. Ke hoʻomau nei ka ulu ʻana o ka ʻoihana lāʻau lapaʻau, e manaʻo ʻia e piʻi ka noi no 3,4-difluoronitrobenzene, e lilo ia i mea nui no ka wā e hiki mai ana o ka hoʻomohala lāʻau.
