Chemical Structure
Description
2-(3-((4-Chlorophenyl)sulfonyl)propanamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (CAS 771506-62-8), molecular formula C18H19ClN2O4S2 and molecular weight 426.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-((4-Chlorophenyl)sulfonyl)propanamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (C18H19ClN2O4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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 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.
