Pentafluorophenol CAS 771-61-9
ʻO ka Pentafluorophenol kahi hui aniani wai fluorinated me ka haʻahaʻa haʻahaʻa haʻahaʻa, he mea koʻikoʻi ia no ka hoʻomākaukau ʻana i nā mea aniani wai kiʻekiʻe. He kūpono loa ia no ka hoʻomākaukau ʻana i nā mea aniani wai monomer fluorinated. Ke hui pū ʻia me ka haʻahaʻa haʻahaʻa a me ka dielectric anisotropy kiʻekiʻe nematic wai aniani, hiki i ka multifluorinated monomer liquid crystal material ke hoʻonui i ka mamao dipole o nā molekala, hoʻemi i ka manawa pane, hoʻomaikaʻi i nā hiʻohiʻona ʻike o nā mea aniani wai, a hoʻonui i ka mālamalama.

ʻO ka Pentafluorophenol kahi mea koʻikoʻi koʻikoʻi i hoʻohana nui ʻia i ka hoʻomākaukau ʻana i ka lāʻau lapaʻau, ke aniani wai, a me ka polymer material intermediates. No ka laʻana, ma nā kahua o ka lāʻau lapaʻau a me nā pesticides, hoʻohana pinepine ʻia ka pentafluorophenol e hoʻomākaukau i nā esters ikaika pentafluorophenyl no ka peptide synthesis, a laila e hoʻoikaika i ka hoʻokumu ʻana i nā paʻa peptide. Hiki ke hoʻohana ʻia nā esters Pentafluorophenol no ka synthesis solid-phase o nā peptides, ka wai-phase synthesis, a me ka pale ʻana i ka amino acid alkyl esters a i ʻole nā hui waikawa sulfonic.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
