ʻO C7H5FN2O2 ka mea hoʻoheheʻe kemika, ʻo ia ka pūhui mea ola. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana: Nature:
he paʻa kalamele melemele. Loaʻa iā ia kahi ʻātoma fluorine a me kahi hui methyl i pani ʻia ma ke apo pyridine, a ua pani ʻia kahi hui nitro ma ke kūlana 3 o ke apo pyridine. He wahi hehee kona ma kahi o 177-180 degere Celsius a paʻa ma ka lumi wela. ʻAʻole hiki ke hoʻoheheʻe ʻia kēia pūhui i ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka methanol, ethanol a me dimethylformamide. Hoʻohana:
He mea nui ia i ka synthesis organik. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he waena i ka synthesis o nā pūhui organik ʻē aʻe. Eia kekahi, hiki ke hoʻohana ʻia e like me nā intermediates dye, pharmaceutical intermediates a me pesticide intermediates. He mea pahū nō hoʻi ma muli o ka loaʻa ʻana o kāna pūʻulu hana nitro.
Hiki ke loaʻa ka hoʻomākaukau ʻana o ka calcium ma ka hana ʻana i ka pyridine me ka Methyl fluoride i mua o ka sodium carbonate, a ukali ʻia e ka nitration. Hiki ke kuhikuhi ʻia nā ʻanuʻu hoʻomākaukau kikoʻī i ka palapala hoʻohuihui organik kūpono.

ʻIke palekana:
No ka mea he pūʻulu hana nitro a hiki ke pahū ma lalo o kekahi mau kūlana, pono e lawe ʻia nā hana palekana i ka wā o ka hana. He hopena hoʻonāukiuki paha ia ma ka maka a me ka ʻili, no laila pono e pale ʻia ka hoʻopili pololei ʻana i ka wā e pili ana. I ka manawa like, e hoʻolohe i ka makū, ke ahi a me ka pale pahū i ka wā mālama a me ka lawe ʻana. No ka hoʻohana pono ʻana a me ka lawelawe ʻana, e ʻoluʻolu e hahai i nā alakaʻi hana palekana o nā kemika kūpono a hana ma lalo o ke alakaʻi ʻana o nā limahana akamai.
