Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Abz-Phe-Arg-Lys(Dnp)-Pro-OH.
CATO supplies Abz-Phe-Arg-Lys(Dnp)-Pro-OH (CAS 500799-61-1), a certified reference material (molecular formula C39H49N11O10, MW 831.89 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Abz-Phe-Arg-Lys(Dnp)-Pro-OH is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 831.89 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).
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.
