Description
As a certified reference material (CRM), H-Gly-Arg-Gly-Asp-Ser-Pro-Lys-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.
H-Gly-Arg-Gly-Asp-Ser-Pro-Lys-OH (CAS 111119-28-9), molecular formula C28H49N11O11 and molecular weight 715.76 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, H-Gly-Arg-Gly-Asp-Ser-Pro-Lys-OH is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 715.76 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
