Pentafluorophenol CAS 771-61-9 yog dab tsi?

Pentafluorophenol yog ib qho tshuaj sib xyaw ua ke ntawm cov kua siv lead ua kua uas muaj ntau cov fluorinated thiab tsis muaj kev cuam tshuam rau cov kua siv lead ua kua. Nws yog qhov tsim nyog rau kev npaj cov khoom siv sib xyaw ua ke ntawm cov kua siv lead ua kua monomer. Thaum sib xyaw nrog cov khoom siv sib xyaw ua ke uas muaj viscosity qis thiab cov khoom siv sib xyaw ua ke uas muaj dielectric anisotropy nematic, cov khoom siv sib xyaw ua ke ntawm cov kua siv lead ua kua monomer tuaj yeem ua rau kom muaj qhov deb ntawm cov molecule dipole, txo lub sijhawm teb, txhim kho cov khoom pom ntawm cov khoom siv sib xyaw ua ke, thiab txhim kho qhov pom tseeb.

Daim Ntawv Thov

Pentafluorophenol yog ib qho tseem ceeb intermediate feem ntau siv rau hauv kev npaj cov tshuaj, kua siv lead ua kua, thiab cov khoom siv polymer intermediates. Piv txwv li, hauv cov teb ntawm kev kho mob thiab tshuaj tua kab, pentafluorophenol feem ntau siv los npaj pentafluorophenyl active esters rau peptide synthesis, yog li txhawb kev tsim cov peptide bonds. Pentafluorophenol esters tuaj yeem siv rau kev tsim cov peptides hauv theem khov, kev tsim cov kua, nrog rau kev tiv thaiv cov amino acid alkyl esters lossis sulfonic acid pawg.
