Pyr-Arg-Thr-Lys-Arg-AMC (CAS 155575-02-3), molecular formula C37H57N13O9 and molecular weight 827.93 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Pyr-Arg-Thr-Lys-Arg-AMC (C37H57N13O9) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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 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).
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.
