Description
CATO supplies (5E)-5,8-Anhydro-2,4-dideoxy-2-diazo-6,7-O-(1-methylethylidene)-9-O-(triphenylmethyl)-L-ribo-3-nonulosonic Acid Ethyl Ester (CAS 206269-72-9), a certified reference material (molecular formula C33H34N2O7, MW 570.63 g/mol) for analytical method development and quality control.
The molecular framework of (5E)-5,8-Anhydro-2,4-dideoxy-2-diazo-6,7-O-(1-methylethylidene)-9-O-(triphenylmethyl)-L-ribo-3-nonulosonic Acid Ethyl Ester (C33H34N2O7) 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.
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.
