Pentafluorophenol

It is widely applied as an activating agent in organic synthesis, particularly for the preparation of esters and peptide coupling reactions. Its strong acidity and leaving-group ability make it a valuable intermediate in pharmaceuticals and agrochemical synthesis. Pentafluorophenol is a highly electron-deficient aromatic phenol where all five hydrogen atoms on the benzene ring are replaced by fluorine atoms.
