Description: CHA is a superior handle for routine preparation of peptide amides, which form the stable dibenzotropylium ion during acidolytic cleavage, especially peptides containing acid labile residues such as Trp and/or Tyr(SO3H). CHA handles incorporated into a polymer support can be rapidly cleaved at lower concentrations of TFA than those required for the PAL handle. The half-lives for cleavage with 25% TFA were <4 min for CHA, 35 min for PAL, and 38 min for RAM. The results show that CHA-peptides can be easily and rapidly cleaved to liberate peptides from polymer support using lower TFA concentrations.
