Ethyl 2-(2,5-dioxo-2,5-dihydro-1h-pyrrol-1-yl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate CAS 62159-47-1

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.

Ethyl 2-(2,5-dioxo-2,5-dihydro-1h-pyrrol-1-yl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 62159-47-1) is a high-purity analytical reference standard with the molecular formula C15H15NO4S and a molecular weight of 305.35 g/mol.

Structurally, Ethyl 2-(2,5-dioxo-2,5-dihydro-1h-pyrrol-1-yl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (C15H15NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 305.35 g/mol, it falls into the moderately-high-molecular-weight range. 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).

As a certified reference material (CRM), Ethyl 2-(2,5-dioxo-2,5-dihydro-1h-pyrrol-1-yl)-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.
