Pentafluorophenol Chemical Properties,Uses,Production
Description
Pentafluorophenol can be used for the preparation of penta-fluorophenyl esters for peptide synthesis. It is used in the preparation of pentafluorophenyl esters for peptide synthesis and vulcanized polymers. It is also used for peptide coupling and heterocyclic acid derivatives. It is involved in the preparation of pentafluorophenyl formate which acts as a formulating agent for amines and amino acids. It can be used for synthesizing novel reagents which can achieve highly diastereoselective acetal cleavage.

Purification Methods
Pentafluorophenol is a hygroscopic low melting solid not freely soluble in H2O. Purify it by distillation, preferably in a vacuum [Forbes et al. J Chem Soc 2019 1959, IR and pKa: Birchall & Haszeldine J Chem Soc 13 1959]. IRofafilmhas max 3600 (OH) and 1575 (fluoroaromatic breathing) cm-1 . The benzoyl derivative has m 74-75o, 3,4-dinitrobenzoyl derivative has m 107o, the tosylate has m 64-65o (from EtOH) and the K salt crystallises from Me2CO, m 242o(dec), with 1H2O-salt the m is 248o(dec) and the 2H2O-salt has m 245o(dec).
