2,2,2-TRIFLUOROETHYL TRIFLUOROACETATE CAS: 407-38-5

2,2,2-Trifluoroethyl trifluoroacetate (TFETA) yog ib qho tshuaj sib xyaw ua ke nrog cov khoom siv tshuaj sib txawv uas pab txhawb nws cov txiaj ntsig dav hauv ntau yam kev siv hauv kev lag luam. Cov Khoom TFETA yog tus cwj pwm los ntawm nws cov qauv molecular, muaj ib pawg trifluoroethyl (-CF3CH2-) txuas nrog rau trifluoroacetate ester (-OC (O) CF3). Kev sib xyaw ua ke no ua rau cov kua ntshiab, tsis muaj xim nrog lub ntsiab lus kub siab, nyob ib puag ncig 145 ° C, thiab solubility zoo heev hauv cov kuab tshuaj organic. Cov tshuaj no ua rau muaj kev cuam tshuam tsawg vim yog qhov xwm txheej ntawm cov electron-withdrawal ntawm cov fluorine atoms, muab kev ruaj khov tshuaj lom neeg nyob rau hauv ntau yam mob. Cov khoom ntawm TFETA ua rau nws tsim nyog rau cov ntawv thov uas xav tau inertness, xws li hauv kev tsim cov khoom nruab nrab ruaj khov thiab cov txheej txheem tiv thaiv. Siv Organic Synthesis: TFETA ua haujlwm ua ib qho tseem ceeb hauv cov organic synthesis, qhov twg nws koom nrog hauv cov tshuaj tiv thaiv los qhia cov haujlwm fluorinated rau hauv cov molecules nyuaj. Lub peev xwm no muaj txiaj ntsig tshwj xeeb hauv kev tshuaj lom neeg rau kev tsim cov tshuaj fluorinated thiab hauv kev tsim cov tshuaj tshwj xeeb qhov twg kev ruaj khov thiab kev tiv thaiv tshuaj xav tau. Kev Tshawb Fawb Txog Cov Khoom Siv: Kev ruaj khov ntawm tshuaj lom neeg thiab kev yaj ntawm TFETA ua rau nws yog ib qho khoom zoo tshaj plaws hauv kev tsim cov txheej thiab cov ntaub ntawv nrog cov kev xav tau tshwj xeeb. Nws yog siv los txhim kho qhov ruaj khov thiab cov khoom tiv thaiv ntawm cov nplaim tiv thaiv kev puas tsuaj ib puag ncig thiab kev tawm tsam tshuaj lom neeg, pab txhawb rau lub neej ntev ntawm cov ntaub ntawv hauv cov ntawv thov xws li cov txheej txheem tsheb mus rau cov khoom siv hluav taws xob. Daim Ntawv Thov Tshuaj: TFETA lub luag haujlwm hauv kev tsim cov organic txuas mus rau cov ntawv thov tshuaj, qhov twg nws cov qauv fluorinated tuaj yeem hloov kho cov haujlwm biological thiab cov khoom pharmacokinetic ntawm cov tshuaj molecules. Qhov no ua rau nws yog ib qho cuab yeej muaj txiaj ntsig hauv kev tshawb pom tshuaj thiab cov txheej txheem tsim kho uas tsom mus rau kev txhim kho kev kho mob zoo thiab bioavailability. Kev Tsim TFETA yog tsim los ntawm esterification ntawm trifluoroacetic acid (CF3COOH) nrog 2,2,2-trifluoroethanol (CF3CH2OH) nyob rau hauv cov xwm txheej acidic. Cov tshuaj tiv thaiv tsim TFETA nrog rau dej ua cov khoom lag luam, uas tuaj yeem ua kom huv si ntawm kev distillation lossis cov kuab tshuaj extraction kom ua tiav qhov huv si siab haum rau cov ntawv thov kev lag luam. Kev tsim thiab kev tuav ntawm TFETA ncaj qha pab txhawb rau nws cov nqi-zoo thiab kev siv dav dav thoob plaws ntau qhov chaw xav tau cov tshuaj fluorinated. Hauv kev xaus lus, 2,2,2-trifluoroethyl trifluoroacetate yog ib qho tshuaj sib xyaw ua ke uas tseem ceeb rau kev tsim cov organic synthesis, cov ntaub ntawv tshawb fawb, thiab cov tshuaj lom neeg. Nws cov khoom siv tshuaj lom neeg tshwj xeeb ua rau muaj peev xwm tsim cov ntaub ntawv siab heev thiab cov tshuaj nrog kev ruaj khov thiab kev ua tau zoo dua, qhia txog nws qhov tseem ceeb hauv kev siv niaj hnub no.
