Hoʻolauna:

2-(trifluoromethyl)ʻakika isonicotinic. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

ʻAno maikaʻi:
ʻO 2-(trifluoromethyl) isonicotinic acid he keʻokeʻo a ʻeleʻele melemele paʻa, ʻo ia ka mea hoʻololi kemika isoniacinic acid derivative. Hoʻoheheʻe ia i nā mahana kiʻekiʻe a hana i nā paʻakai me kekahi mau metala. Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau e like me ka wai, nā waiʻona, a me nā ethers.

Hoʻohana: Hoʻohana nui ia i ka hana ʻana i nā pesticides, fungicides, a me nā herbicides.

Hanana:
Hiki ke loaʻa ka hoʻomākaukau ʻana o 2-(trifluoromethyl) isonicotinic acid ma ka hopena o ka waika isonicotinic me trifluoromethylsulfonate a i ʻole ammonium trifluoromethylsulfonate. Lawe ʻia ka hopena ma lalo o nā kūlana acidic a hoʻopaʻa ʻia me ka hoʻohana ʻana i nā solvents a me nā catalysts kūpono.

ʻIke palekana:
ʻO 2-(Trifluoromethyl) isonicotinic acid he mea ʻawaʻawa loa, akā pono e mālama ʻia me ka akahele. I ka wā o ke kaʻina hana, pono e pale i ka inhalation, pili me ka ʻili a me nā maka. Ke mālama ʻia a mālama ʻia, pono e hoʻokaʻawale ʻia mai nā kemika ʻē aʻe e pale aku i ka hoʻopili ʻana me nā mea oxidizing. E hahai i nā kaʻina hana palekana a hoʻohana i nā mea pale pilikino e like me nā mīkina lima, nā aniani, a me nā ʻaʻahu lab. I ka lawelawe ʻana a i ʻole ka hoʻopau ʻana, pono e mālama ʻia nā lula a me nā lula kūloko.
