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.
(2R,3S,4S,5S,6R)-2-(((2R,3S,4S,5R,6R)-3,5-dihydroxy-2-(4-nitrophenoxy)-6-((((2S,3S,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)methyl)tetrahydro-2H-pyran-4-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (CAS 443346-78-9) is a high-purity analytical reference standard with the molecular formula C24H35NO18 and a molecular weight of 625.53 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (2R,3S,4S,5S,6R)-2-(((2R,3S,4S,5R,6R)-3,5-dihydroxy-2-(4-nitrophenoxy)-6-((((2S,3S,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)methyl)tetrahydro-2H-pyran-4-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 625.53 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
