Pentafluorophenol CAS 771-61-9
Pentafluorophenol ndi multifluorinated liquid crystal pawiri yokhala ndi chotchinga chochepa kwambiri, chomwe ndi chofunikira chapakatikati pokonzekera zida zamadzimadzi zamadzimadzi zogwira ntchito kwambiri. Ndi makamaka oyenera yokonza Mipikisano fluorinated monoma madzi galasi zipangizo. Mukasakanizidwa ndi kukhuthala kotsika komanso zida zapamwamba za dielectric anisotropy nematic liquid crystal, zida zamadzimadzi zamadzimadzi zamitundu yambiri zimatha kuwonjezera mtunda wa dipole wa mamolekyu, kuchepetsa nthawi yoyankha, kusintha mawonekedwe azinthu zamadzimadzi zamadzimadzi, ndikuwongolera kumveka bwino.

Pentafluorophenol ndi yofunika wapakatikati makamaka ntchito yokonza mankhwala, madzi krustalo, ndi polima zakuthupi intermediates. Mwachitsanzo, m'minda yamankhwala ndi mankhwala ophera tizilombo, pentafluorophenol nthawi zambiri amagwiritsidwa ntchito pokonzekera pentafluorophenyl esters yogwira ntchito ya peptide synthesis, potero kulimbikitsa mapangidwe a peptide. Pentafluorophenol esters angagwiritsidwe ntchito olimba-gawo kaphatikizidwe ma peptides, madzi-gawo kaphatikizidwe, komanso kuteteza amino acid alkyl esters kapena sulfonic acid magulu.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
