Ethyl 3-(N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)sulfamoyl)benzo[b]thiophene-2-carboxylate CAS 932520-20-2 chemical structure

Description

The occurrence of Ethyl 3-(N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)sulfamoyl)benzo[b]thiophene-2-carboxylate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 3-(N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)sulfamoyl)benzo[b]thiophene-2-carboxylate (CAS 932520-20-2), a certified reference material (molecular formula C19H17NO6S2, MW 419.47 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 3-(N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)sulfamoyl)benzo[b]thiophene-2-carboxylate (C19H17NO6S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
