Chemical Structure

4H-1-Benzopyran-4-one, 3-[(6-deoxy-4-O-α-D-xylopyranosyl-α-L-mannopyranosyl)oxy]-7-(β-D-glucopyranosyloxy)-5-hydroxy-2-(4-methoxyphenyl)-8-(3-methyl-2-butenyl)- CAS 133137-58-3 chemical structure

Description

CATO supplies 4H-1-Benzopyran-4-one, 3-[(6-deoxy-4-O-α-D-xylopyranosyl-α-L-mannopyranosyl)oxy]-7-(β-D-glucopyranosyloxy)-5-hydroxy-2-(4-methoxyphenyl)-8-(3-methyl-2-butenyl)- (CAS 133137-58-3), a certified reference material (molecular formula C38H48O19, MW 808.78 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4H-1-Benzopyran-4-one, 3-[(6-deoxy-4-O-α-D-xylopyranosyl-α-L-mannopyranosyl)oxy]-7-(β-D-glucopyranosyloxy)-5-hydroxy-2-(4-methoxyphenyl)-8-(3-methyl-2-butenyl)- is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 808.78 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.

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.
