CATO supplies (2R,4S,5R,6R)-5-Acetamido-2-(((2R,3R,4R,5R,6S)-5-acetamido-6-((S)-2-acetamido-2-carboxyethoxy)-3,4-dihydroxytetrahydro-2H-pyran-2-yl)methoxy)-4-hydroxy-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylic acid (CAS 385398-89-0), a certified reference material (molecular formula C24H39N3O17, MW 641.58 g/mol) for analytical method development and quality control.
(2R,4S,5R,6R)-5-Acetamido-2-(((2R,3R,4R,5R,6S)-5-acetamido-6-((S)-2-acetamido-2-carboxyethoxy)-3,4-dihydroxytetrahydro-2H-pyran-2-yl)methoxy)-4-hydroxy-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylic acid (C24H39N3O17) contains a flavonoid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
