ʻO Ammonium trifluoroacetate, ʻike ʻia hoʻi ʻo NH4TFA, he mea hoʻohui kemika me ka molecular formula C2H2F3O2NH4.He paʻa keʻokeʻo keʻokeʻo i hiki ke hoʻoheheʻe ʻia i ka wai.Loaʻa ka Ammonium trifluoroacetate i nā noi he nui i nā ʻoihana like ʻole ma muli o kāna mau ʻano a me nā ʻano.He kumu kūpono ia o ka anion trifluoroacetate i nā hopena.Hiki i ka anion trifluoroacetate ke hana ma ke ʻano he nucleophile, komo i ka hoʻololi a me ka hoʻohui ʻana i nā hopena, a i ʻole ma ke ʻano he waikawa nāwaliwali i kekahi mau hihia.ʻO kāna hana hoʻomalu a me ka haʻahaʻa haʻahaʻa e lilo ia i mea waiwai nui i nā loli kūlohelohe.Hiki iā ia ke hoʻolōʻihi i nā hopena ma ka hāʻawi ʻana i kahi ala ʻē aʻe me ka ikehu hoʻāla haʻahaʻa.Hoʻohana nui kēia i nā hopena e pili ana i nā ʻakika carboxylic a me kā lākou derivatives, kahi e hiki ai ke hoʻonui i ka wikiwiki o ka esterification, amidation, a me nā hopena condensation ʻē aʻe.Hoʻohana maʻamau ia i nā ʻenehana chromatography-mass spectrometry (LC-MS) no ka hoʻokaʻawale ʻana a me ka ʻike ʻana i nā protein, peptides, a me nā waikawa nucleic.Hana ʻia ka Ammonium trifluoroacetate ma ke ʻano he ion-pairing reagent, hoʻomaikaʻi i ka hoʻonā chromatographic a hoʻonui i ka ʻike o ka ʻike.Hiki ke hoʻohana ʻia ma ke ʻano he buffering agent a me ka pH regulator i ka hoʻokumu ʻana i nā lāʻau lapaʻau a me nā ʻōnaehana lawe lāʻau.ʻO ka hoʻokomoʻana i ka ammonium trifluoroacetate hiki ke kōkua i ka mālamaʻana i ka paʻa a me ka solubility o nā mea lāʻau lapaʻau ikaika (API) i nāʻano hoʻohālike likeʻole. Hoʻohana pūʻia ka Ammonium trifluoroacetate ma ke kahua o ka electrochemistry.Hiki iā ia ke hoʻonui i ka hana o nā cell electrochemical ma ka hana ʻana ma ke ʻano he electrolyte additive.Ma ka hoʻomaikaʻi ʻana i ka lawe ʻana i ka ion a me ka paʻa ʻana i nā pilina electrode, hāʻawi ka ammonium trifluoroacetate i ka maikaʻi a me ka lōʻihi o nā pihi, nā wahie, a me nā mea electrochemical ʻē aʻe.Hiki ke hoʻohana ʻia ma ke ʻano he mea paʻakikī i nā kaʻina hana hoʻoheheʻe metala, e kōkua ana i ka waiho ʻana o nā uhi metala ma nā substrate like ʻole.ʻO ka hoʻohana ʻana i ka ammonium trifluoroacetate hiki ke alakaʻi i ka hoʻopili maikaʻi ʻana, ka pale ʻana i ka corrosion, a me ke ʻano o ka ʻili o ka metala i hoʻopaʻa ʻia. hoʻopau metala.ʻO kāna hana ʻana, hiki ke hoʻopaʻa, a me nā waiwai paʻakikī e lilo ia i mea waiwai nui i nā ʻoihana like ʻole, e hāʻawi ana i nā holomua i ka chemistry, material science, a me ka ʻenehana.
