Mini-Spotlight: Fmoc-MeDbz

Fmoc-MeDbz (FMD-2331) is a useful linker in peptide synthesis, and, in particular, in preparing key C-terminal peptide thioester intermediates in native chemical ligation (NCL). The MeDbz group is also less prone to acetylation during sold-phase peptide synthesis (SPPS) than the first generation Nbz linker.

Synonym: 3-[(9-Flurenylmethyloxycarbonyl)Amino]-4-(Methylamino)Benzoic Acid

CAS Number: 1788861-35-7
