(2S,3S,4S,5R,6S)-Methyl 3,4,5-trihydroxy-6-((5-hydroxy-8-methoxy-4-oxo-2-phenyl-4H-chromen-7-yl)oxy)tetrahydro-2H-pyran-2-carboxylate CAS 82475-01-2 chemical structure

Description

CATO supplies (2S,3S,4S,5R,6S)-Methyl 3,4,5-trihydroxy-6-((5-hydroxy-8-methoxy-4-oxo-2-phenyl-4H-chromen-7-yl)oxy)tetrahydro-2H-pyran-2-carboxylate (CAS 82475-01-2), a certified reference material (molecular formula C23H22O11, MW 474.41 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, (2S,3S,4S,5R,6S)-Methyl 3,4,5-trihydroxy-6-((5-hydroxy-8-methoxy-4-oxo-2-phenyl-4H-chromen-7-yl)oxy)tetrahydro-2H-pyran-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 474.41 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).

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.
