Application
Pentafluorophenyl trifluoroacetate can be used:
- In the esterification of 2′-carboxyrhodamine dye to form pentafluorophenyl ester as a single isomer.
- As an acylating agent and a coupling agent for the peptide-type coupling of N-substituted glycine oligomers.
- In the synthesis of pentafluorophenyl thiophene-3-acetate (PFPTA) by reacting with 3-thiopheneacetic acid.
Other Notes
may contain a small amount of pentafluorophenol
