Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 221.28 g/mol gives N-Methoxy-N-methylbenzo[b]thiophene-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-Methoxy-N-methylbenzo[b]thiophene-2-carboxamide (CAS 279226-22-1), a certified reference material (molecular formula C11H11NO2S, MW 221.28 g/mol) for analytical method development and quality control.
The molecular framework of N-Methoxy-N-methylbenzo[b]thiophene-2-carboxamide (C11H11NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-Methoxy-N-methylbenzo[b]thiophene-2-carboxamide 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.
