Description
7-(((2S,3R,4R,5S,6R)-3,4-Dihydroxy-6-(hydroxymethyl)-5-methoxytetrahydro-2H-pyran-2-yl)oxy)-5-hydroxy-3-(4-hydroxyphenyl)-4H-chromen-4-one (CAS 950910-16-4), molecular formula C22H22O10 and molecular weight 446.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 7-(((2S,3R,4R,5S,6R)-3,4-Dihydroxy-6-(hydroxymethyl)-5-methoxytetrahydro-2H-pyran-2-yl)oxy)-5-hydroxy-3-(4-hydroxyphenyl)-4H-chromen-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 446.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
