Description
As a certified reference material (CRM), Cyclo(-Arg-Gly-Asp-D-Tyr-Lys) 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.
Cyclo(-Arg-Gly-Asp-D-Tyr-Lys) (CAS 217099-14-4), molecular formula C27H41N9O8 and molecular weight 619.68 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, Cyclo(-Arg-Gly-Asp-D-Tyr-Lys) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 619.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
