Chemical Structure

Fmoc-D-Arg (Pbf)-OH CAS 187618-60-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 648.77 g/mol gives Fmoc-D-Arg (Pbf)-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Fmoc-D-Arg (Pbf)-OH (CAS 187618-60-6), a certified reference material (molecular formula C34H40N4O7S, MW 648.77 g/mol) for analytical method development and quality control.

The molecular framework of Fmoc-D-Arg (Pbf)-OH (C34H40N4O7S) 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Fmoc-D-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.
