H-Phe-Pro-Arg-OH CAS 37553-80-3

Description

The occurrence of H-Phe-Pro-Arg-OH is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies H-Phe-Pro-Arg-OH (CAS 37553-80-3), a certified reference material (molecular formula C20H30N6O4, MW 418.49 g/mol) for analytical method development and quality control.

The molecular framework of H-Phe-Pro-Arg-OH (C20H30N6O4) is characterized by a flavonoid core, 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 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.

As a certified reference material (CRM), H-Phe-Pro-Arg-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.
