Chemical Structure
Description
(3AR,5R,6S,6aR)-5-(((methoxycarbonyl)oxy)methyl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-6-yl 4-methylbenzenesulfonate (CAS 74580-94-2) is a high-purity analytical reference standard with the molecular formula C17H22O9S and a molecular weight of 402.42 g/mol.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, (3AR,5R,6S,6aR)-5-(((methoxycarbonyl)oxy)methyl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-6-yl 4-methylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 402.42 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.
