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.

ADP-ribosylation is essential for cell function, yet there is a dearth of methods for detecting this post-translational modification in cells. Here, we describe a clickable aminooxy alkyne (AO-alkyne) probe that can detect cellular ADP-ribosylation on acidic amino acids following Cu-catalyzed
