Description

General description

Fmoc-Arg(Pbf)-OH is used as a building block in peptide synthesis, providing protection to specific functional groups while allowing for efficient peptide bond formation.

Application

Fmoc-Arg(Pbf)-OH is a Fmoc-protected amino acid derivative that can be used to create arginine-containing peptides. The 2,2,4,6,7-pentamethyIdlhydrobenzofuran-5-sulfonyl group (Pbf) can be easily cleaved by trifluoroacetic acid (TFA).
