Pentafluorophenol CAS 771-61-9
Pentafluorophenol jẹ ohun elo olomi olomi fluorinated pupọ pẹlu idiwọ sitẹriki kekere, eyiti o jẹ agbedemeji pataki fun ngbaradi awọn ohun elo kirisita olomi-giga. O dara ni pataki fun igbaradi ti ọpọlọpọ awọn ohun elo kirisita olomi monomer fluorinated. Nigbati o ba dapọ pẹlu iki kekere ati dielectric anisotropy nematic omi gara awọn ohun elo, ọpọlọpọ awọn ohun elo kirisita olomi monomer fluorinated le ṣe alekun ijinna dipole ti awọn ohun elo, dinku akoko idahun, mu awọn ohun-ini wiwo ti awọn ohun elo kirisita olomi dara, ati imudara mimọ.

Pentafluorophenol jẹ agbedemeji pataki pataki ti a lo ni igbaradi ti oogun, kirisita omi, ati awọn agbedemeji ohun elo polima. Fun apẹẹrẹ, ni awọn aaye ti oogun ati awọn ipakokoropaeku, pentafluorophenol nigbagbogbo lo lati ṣeto awọn esters ti nṣiṣe lọwọ pentafluorophenyl fun iṣelọpọ peptide, nitorinaa igbega dida awọn ifunmọ peptide. Pentafluorophenol esters le ṣee lo fun kolaginni-alakoso ti peptides, olomi-akoko kolaginni, bi daradara bi fun aabo amino acid alkyl esters tabi sulfonic acid awọn ẹgbẹ.
Nigbagbogbo aba ti ni 25kg / ilu, ati tun le ṣee ṣe package ti adani.
