Description

General description

Ramage Amide AM resin comprises Ramage′s dibenzocycloheptadienelinker ^[1] attached to aminomethylated polystyrene. Following Fmoc removal, the resin can be acylated under standard conditions and used in Fmoc SPPS. The linker is considerably more acid sensitive than the Rink amide or PAL linkers. This enables peptide amides to be released from the resin with 3% TFA in DCM and thus makes it a useful tool for the synthesis of acid sensitive peptides or protected peptide fragments.
