Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 425.45 g/mol gives Methyl 3-(N-(3,4-dimethoxyphenyl)sulfamoyl)-4-fluorobenzo[b]thiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 3-(N-(3,4-dimethoxyphenyl)sulfamoyl)-4-fluorobenzo[b]thiophene-2-carboxylate (CAS 932464-87-4), a certified reference material (molecular formula C18H16FNO6S2, MW 425.45 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Methyl 3-(N-(3,4-dimethoxyphenyl)sulfamoyl)-4-fluorobenzo[b]thiophene-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 425.45 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
