Pentafluorophenol is the organofluorine compound (specifically a fluoroalcohol) with the formula C₆F₅OH. It is a colorless solid that melts just above room temperature. With a pKa of 5.5, it is one of the most acidic phenols. It is used to prepare pentafluorophenyl esters, which are active esters useful in peptide synthesis.[1]
