Fmoc-Arg(Pbf)-OH

• CAS: 154445-77-9
• Catalog Number: ACM154445779-1
• Category: Amino Acids
• Molecular Weight: 648.77
• Molecular Formula: C34H40N4O7S
• Description: High purity Fmoc-protected amino acid for research and process production of peptides, with very low levels of dipeptide, free-amino acids and acetic acid impurities.; The standard derivative for the introduction of Arg in Fmoc SPPS. The Pbf side-chain protecting group is removed with TFA approximately 1-2 times faster than Pmc.In the preparation of peptides containing both Arg and Trp, it is recommended that this derivative is used in conjunction with Fmoc-Trp(Boc)-OH.
