General description

Pentafluorophenol is widely used as a precursor in both solution and solid-phase peptide synthesis. It is also involved in the preparation of aromatic fluoro derivatives.

Application

Pentafluorophenol can be used as a reactant to synthesize pentafluorophenyl esters from:
  • N-protected amino acid in the presence of dicyclohexylcarbodiimide and ethyl acetate.
  • t-Butoxycarbonyl-L-alanylglycinein the presence of 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride.
  • Aliphatic dicarboxylic acids in the presence of pyridine, diisopropylcarbodiimide, and acetonitrile.
It can also be used as a reactant to synthesize pentafluorophenyl formate which can be used as a formylating agent in organic synthesis.

A mixture of 5- and 6-carboxyfluorescein was activated with 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride in the presence of either N-hydroxysuccinimide or pentafluorophenol to give the corresponding succinimidyl and pentafluorophenyl esters. The regioisomeric mixtures were separated to give the 5- and 6-succinimidyl and pentafluorophenyl
