Chemical Structure

Z-D-Phe-Arg-OH CAS 88831-05-4 chemical structure

Description

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Z-D-Phe-Arg-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 455.51 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).

CATO supplies Z-D-Phe-Arg-OH (CAS 88831-05-4), a certified reference material (molecular formula C23H29N5O5, MW 455.51 g/mol) for analytical method development and quality control.

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.

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.
