Chemical Structure
Description
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 3-((4-(5-chloro-2-methylphenyl)piperazin-1-yl)sulfonyl)benzo[b]thiophene-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 479.01 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).
Ethyl 3-((4-(5-chloro-2-methylphenyl)piperazin-1-yl)sulfonyl)benzo[b]thiophene-2-carboxylate (CAS 932520-35-9), molecular formula C22H23ClN2O4S2 and molecular weight 479.01 g/mol, is a CATO reference standard with documented purity and traceability.
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), Ethyl 3-((4-(5-chloro-2-methylphenyl)piperazin-1-yl)sulfonyl)benzo[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.
