H-Gly-Arg-Gly-Asp-Thr-Pro-OH CAS 108682-58-2

Description

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.

H-Gly-Arg-Gly-Asp-Thr-Pro-OH (CAS 108682-58-2), molecular formula C23H39N9O10 and molecular weight 601.61 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, H-Gly-Arg-Gly-Asp-Thr-Pro-OH is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 601.61 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
