The CAS number of Pentafluorophenol is 771-61-9.

What is Pentafluorophenol (771-61-9) used for?

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.InChI:InChI=1/C6HF5O.K/c7-1-2(8)4(10)6(12)5(11)3(1)9;/h12H;/q;+1/p-1
