What is Pentafluorophenol CAS 771-61-9？

Pentafluorophenol is a multi fluorinated liquid crystal compound with low steric hindrance, which is an important intermediate for preparing high-performance liquid crystal materials. It is particularly suitable for the preparation of multi fluorinated monomer liquid crystal materials. When mixed with low viscosity and high dielectric anisotropy nematic liquid crystal materials, multi fluorinated monomer liquid crystal materials can increase the dipole distance of molecules, reduce response time, improve the visual properties of liquid crystal materials, and enhance clarity

Ứng dụng

Pentafluorophenol is an important intermediate mainly used in the preparation of pharmaceutical, liquid crystal, and polymer material intermediates. For example, in the fields of medicine and pesticides, pentafluorophenol is often used to prepare pentafluorophenyl active esters for peptide synthesis, thereby promoting the formation of peptide bonds. Pentafluorophenol esters can be used for solid-phase synthesis of peptides, liquid-phase synthesis, as well as for protecting amino acid alkyl esters or sulfonic acid groups.
