Description

(2S,​4aR,​6aR,​7R,​9S,​10aS,​10bR)​-2-​(3-​Furanyl)​dodecahydro-​6a,​10b-​dimethyl-​9-​[(methylsulfonyl)​oxy]​-​4,​10-​dioxo-2H-​Naphtho[2,​1-​c]​pyran-​7-​carboxylic Acid Methyl Ester (C22H28O9S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies (2S,​4aR,​6aR,​7R,​9S,​10aS,​10bR)​-2-​(3-​Furanyl)​dodecahydro-​6a,​10b-​dimethyl-​9-​[(methylsulfonyl)​oxy]​-​4,​10-​dioxo-2H-​Naphtho[2,​1-​c]​pyran-​7-​carboxylic Acid Methyl Ester (CAS 862073-79-8), a certified reference material (molecular formula C22H28O9S, MW 468.52 g/mol) for analytical method development and quality control.

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.
