Chemical Structure

Fmoc-Arg(Pbf)-Arg(Pbf)-OH CAS 1589085-71-1 chemical structure

Description

The molecular framework of Fmoc-Arg(Pbf)-Arg(Pbf)-OH (C53H68N8O11S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Fmoc-Arg(Pbf)-Arg(Pbf)-OH (CAS 1589085-71-1), molecular formula C53H68N8O11S2 and molecular weight 1057.28 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Fmoc-Arg(Pbf)-Arg(Pbf)-OH meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
