Chemical Structure

Fmoc-Val-D-Cit-PAB CAS 1350456-67-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 601.69 g/mol gives Fmoc-Val-D-Cit-PAB distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Fmoc-Val-D-Cit-PAB (CAS 1350456-67-5), molecular formula C33H39N5O6 and molecular weight 601.69 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Fmoc-Val-D-Cit-PAB is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 601.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-Val-D-Cit-PAB 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.
