H-Gly-Arg-Gly-Asp-Ser-Pro-Cys-OH CAS 91575-26-7

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-Ser-Pro-Cys-OH (CAS 91575-26-7), molecular formula C25H42N10O11S and molecular weight 690.73 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of H-Gly-Arg-Gly-Asp-Ser-Pro-Cys-OH (C25H42N10O11S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
