Chemical Structure
Description
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.
CATO supplies (S)-2-(((2R,3R,4S,5S,6R)-3-(Benzoyloxy)-2-(((1R,2R,3S,5R)-3-(2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxamido)-5-((2-(2-(2-(2-oxo-2-((3,6,8-trisulfonaphthalen-1-yl)amino)ethoxy)ethoxy)acetamido)ethyl)carbamoyl)-2-(((2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6- (CAS 1189037-60-2), a certified reference material (molecular formula C58H70N6O31S3Na, MW 1466.38 g/mol) for analytical method development and quality control.
The molecular framework of (S)-2-(((2R,3R,4S,5S,6R)-3-(Benzoyloxy)-2-(((1R,2R,3S,5R)-3-(2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxamido)-5-((2-(2-(2-(2-oxo-2-((3,6,8-trisulfonaphthalen-1-yl)amino)ethoxy)ethoxy)acetamido)ethyl)carbamoyl)-2-(((2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6- (C58H70N6O31S3Na) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
