Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-(2-methoxybenzamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate.
CATO supplies Ethyl 2-(2-methoxybenzamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 300815-09-2), a certified reference material (molecular formula C19H21NO4S, MW 359.44 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-methoxybenzamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.44 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).
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.
As a certified reference material (CRM), Ethyl 2-(2-methoxybenzamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-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.
