Chemical Structure

Ethyl 2-(2-(4-(2-hydroxyethyl)piperazin-1-yl)acetamido)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate CAS 446280-91-7 chemical structure

Description

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.

CATO supplies Ethyl 2-(2-(4-(2-hydroxyethyl)piperazin-1-yl)acetamido)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 446280-91-7), a certified reference material (molecular formula C20H31N3O4S, MW 409.54 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, Ethyl 2-(2-(4-(2-hydroxyethyl)piperazin-1-yl)acetamido)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 409.54 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).

CATO manufactures Ethyl 2-(2-(4-(2-hydroxyethyl)piperazin-1-yl)acetamido)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
