| Pentafluorophenol Usage And Synthesis |
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.

It is involved in the preparation of pentafluorophenyl formate which acts as a formulating agent for amines and amino acids. | 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. | Synthesis Reference(s) | The Journal of Organic Chemistry, 54, p. 5502, 1989 DOI: 10.1021/jo00284a022 | 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. | reaction suitability | reaction type: Addition Reactions | Safety Profile | scu-rat LD50:322 mg/kg IZSBAI 3,91,65 | Purification Methods | Pentafluorophenol is a hygroscopic low melting solid not freely soluble in H2O.
