Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 3-(N-(2,4-dimethoxyphenyl)sulfamoyl)-4-fluorobenzo[b]thiophene-2-carboxylate (CAS 932354-43-3) is a high-purity analytical reference standard with the molecular formula C18H16FNO6S2 and a molecular weight of 425.45 g/mol.
The molecular framework of Methyl 3-(N-(2,4-dimethoxyphenyl)sulfamoyl)-4-fluorobenzo[b]thiophene-2-carboxylate (C18H16FNO6S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Methyl 3-(N-(2,4-dimethoxyphenyl)sulfamoyl)-4-fluorobenzo[b]thiophene-2-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
