Pentafluorophenol is the organofluorine compound (specifically a fluoroalcohol) with the formula C6F5OH. This is the perfluorinated analogue of phenol. It is a white odorless solid that melts just above room temperature. With a pKa of 5.5, it is one of the most acidic phenols.

Uses[edit]

Pentafluorophenol is used to prepare pentafluorophenyl esters, which are active esters useful in peptide synthesis.[1]

Environmental hazards[edit]

Pentafluorophenol is considered hazardous because of oral, dermal and inhalation toxicity and because it causes severe skin burns and eye damage.[2][3]
