Ko te konutai trifluoroacetate (NaCF3CO2) he puhui matū e whakamahia nuitia ana i roto i nga momo ahumahi me nga waahi taiwhanga na ona ahuatanga ahurei.Ko te totoka tioata ma e tino whakarewahia ana i roto i te wai me nga whakarewa pararopi polar.Ko tetahi o nga whakamahinga tuatahi o te konutai trifluoroacetate hei reagent i roto i te whakahiato waro.Ka taea te whakamahi hei puna o te roopu trifluoroacetyl (-COCF3) i roto i nga momo tauhohenga.Ko te roopu trifluoroacetyl e mohiotia ana mo tona ahua me te pumau o te tango irahiko, ka whai hua ki te whakahiatotanga o nga rongoa, agrochemicals, me etahi atu matū pai.Ka taea te whakamahi konutai trifluoroacetate, hei tauira, i roto i te acylation o amine, waipiro, me te thiols, e arai ana ki te hanganga o nga takawaenga nui, hua whakamutunga ranei. I tua atu, ko te konutai trifluoroacetate te nuinga o te mahi i roto i te whakahiato o nga pūhui fluorinated.Ko te whakaurunga o nga ngota fluorine ki roto i nga ngota rauropi ka taea te whakarei ake i o raatau ahuatanga o te tinana me te matū, penei i te piki o te lipophilicity, te pumau, me te mahi koiora.Ko te konutai trifluoroacetate he mea nui mo te whakaurunga o nga roopu trifluoroacetyl ki roto i nga puhui pararopi, e taea ai te whakahiato o nga rongoā fluorinated, agrochemicals, me te polymers. I tua atu i tana mahi hei reagent, ka whakamahia ano te sodium trifluoroacetate hei whakakorikori i etahi tauhohenga. .Ka taea te mahi hei whakakorikori waikawa Lewis, e whakatairanga ana i nga momo panoni penei i te Friedel-Crafts acylation me nga tauhohenga condensation aldol.Ko tana kaha ki te whakahohe i etahi taputapu me te whakahaere i nga huarahi tauhohenga he taputapu nui i roto i te matū waihanga. I tua atu, ka kitea e te konutai trifluoroacetate nga tono ki etahi atu waahi penei i te matū tātari.Ka taea te whakamahi hei rauemi tohutoro paerewa mo te whakahiatotanga o te resonance autō karihi (NMR).Ko te konutai trifluoroacetate he pai te tautuhi i nga tihi NMR, e whai hua ana mo te whakatikatika i nga taputapu NMR me te arotake i o raatau mahi. Hei whakarāpopototanga, ko te konutai trifluoroacetate he puhui maha me nga momo whakamahinga i roto i te whakahiato waro, tauhohenga fluorination, me te catalysis.Ko tana kaha ki te mahi hei puna o te roopu trifluoroacetyl me tona pumau ka waiho hei reagent utu nui mo te whakahiato o nga rongoa, matū ahuwhenua, me etahi atu matū pai.I tua atu, ko tana mahi hei whakakorikori me tana tono i roto i te matū tātaritanga e whakaatu ana i tana whaipainga ki nga waahi taiwhanga rereke.
