Description

(3S,3aS,6R,6aS)-6-{[(4-methylbenzene)sulfonyl]oxy}-hexahydrofuro[3,2-b]furan-3-yl 4-methylbenzene-1-sulfonate 66966-12-9 KS-00002BDF (CAS 66966-12-9), molecular formula C20H22O8S2 and molecular weight 454.51 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (3S,3aS,6R,6aS)-6-{[(4-methylbenzene)sulfonyl]oxy}-hexahydrofuro[3,2-b]furan-3-yl 4-methylbenzene-1-sulfonate 66966-12-9 KS-00002BDF (C20H22O8S2) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
