Cov Qauv Tshuaj lom neeg & piav qhia
3, {4- difluorophenol 丨 CAS 2713-33-9 yog afluorinated aromatic compoundFeaturing phenol nplhaib hloov nrog cov tshuaj fluorine atom ntawm 3 thiab 4 txoj haujlwm. Lub xub ntiag ntawm covKev-rho tshuaj fluorine atomshloov kho ntau qhovkev xav tau, cov acidion, thiablipophilicityntawm cov pab pawg phenol, ua rau nws yog ib qho tseem ceeb hauvKev Siv Tshuaj Kho Mob Tshuajthiabzoo tshuaj lom neeg tshuaj synthesis.
Cov Ntawv Thov
1. Tshuaj Nruab Nrab
Dav siv nyob rau hauv lubKhoom cua ntawm cov khoom xyaw tshuaj xyaw (APIS)thiabCov tebchaw bioaction.
Cov Difluoro Hloov Kev Txiaj Ntsigmetabolic ruaj khovthiabBinding Affinityhauv cov neeg sib tw tshuaj.
Ua raws li ib tug ua ntej lossis lub tsev thaiv kev npaj ntawmLos tiv thaiv, tshuaj ntxuav, lossisnyob rautus sawv cev.
2. Agochnical synthesis
Siv nyob rau hauv tus qauv thiab tsim khoom ntawmTshuaj ntsuab, Fungicides, thiabcov tshuaj tua kab.
Cov fluorinated phenol tseem ceeb txhim kho covib puag ncig tsis tu ncuathiabKev ua haujlwm biologicalntawm agnochemicals.
3. Organic synthesis
Ua hauj lwm ua tus yuam sijElectrophilic aromatic intermediate.
Siv nyob rau hauvNucleophilic Aromatic Hloov (SNAR)kev tawm tsam thiabHla kev sib txuas(piv txwv li, Suzuki, Buchwald-Hartwig).
Tuaj yeem txuas ntxiv ntawm cov phenol lossis cov haujlwm uas muaj ntxhiab rau txoj kev zoo siab.
4. Cov Khoom Taw Qhia
Siv nyob rau hauv synthesis ntawmCov tshuaj lom fluorinated polymerslossisresinsQhov twg cov tshuaj kuj, thermal stability, thiab hydrophobicity xav tau.
Ua li ib tug monomer lossis ntxiv rau cov txheej txheem tshwj xeeb thiab cov ntaub ntawv hluav taws xob.
Cov txiaj ntsig
Fluorine hloovNce lipophilicity, siv hluav taws xob-rho tawm cov nyhuv, thiab kev ruaj khov.
Muab kev nkag tau rau ntau yamUa hauj lwm muaj ntxhiab tsw qab.
Pawg Phenol muajkev hloov tau yooj yim(xws li, etheremation, Esterification, txuas).
Lub ntsiab
3, {4- difluorophenol 丨 CAS 2713-33-9yog ib qho tseem ceebfluorinated muaj ntxhiab nyob rau hauv nruab nrabsiv nyob rau hauvKws Tshuaj, agnchemicals, Organic Synthesis, thiabCov Ntaub Ntawv Tshwj XeebCov. Nws lub ntsej muag hluav taws xob tsis txaus tso cai rau cov phiaj xwm kev xav ua kom zoo thiab txhim kho biological cov yam ntxwv hauv qhov kawg-siv cov tebchaw. Nws cov nqi hluav taws xob hauv cov hluavtaws niaj hnub los ntawm cov versatility muab los ntawm cov kev sib dhos hloov cov qauv hloov thiab cov pab pawg pheeb suab.
Qhia rau kuv paub yog tias koj xav tau kev ua piv txwv lossis derivatives synthesized los ntawm cov compound no.
