Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Cyclo(-Gly-Arg-Gly-Glu-Ser-Pro) trifluoroacetate salt is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 697.62 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).
Cyclo(-Gly-Arg-Gly-Glu-Ser-Pro) trifluoroacetate salt (CAS 2022956-43-8), molecular formula C23H37N9O9C2HF3O2 and molecular weight 697.62 g/mol, is a CATO reference standard with documented purity and traceability.
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), Cyclo(-Gly-Arg-Gly-Glu-Ser-Pro) trifluoroacetate salt 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.
