Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(3,4-Dimethoxybenzenesulfonyl)-7-hydroxy-2H-chromen-2-one (CAS 866347-90-2), molecular formula C17H14O7S and molecular weight 362.35 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(3,4-Dimethoxybenzenesulfonyl)-7-hydroxy-2H-chromen-2-one (C17H14O7S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 362.35 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
