Description
CATO supplies N-(S-Nitroso-N-acetyl-D,L-penicillamine)-2-amino-2-deoxy-1,3,4,6-tetra-O-acetyl-β-D-glucopyranose (CAS 202656-49-3), a certified reference material (molecular formula C21H31N3O12S, MW 549.55 g/mol) for analytical method development and quality control.
N-(S-Nitroso-N-acetyl-D,L-penicillamine)-2-amino-2-deoxy-1,3,4,6-tetra-O-acetyl-β-D-glucopyranose (C21H31N3O12S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
