6-Methoxy-2-(thiophen-2-ylmethylene)benzofuran-3(2H)-one CAS 646996-28-3 chemical structure

Description

The occurrence of 6-Methoxy-2-(thiophen-2-ylmethylene)benzofuran-3(2H)-one is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Methoxy-2-(thiophen-2-ylmethylene)benzofuran-3(2H)-one (CAS 646996-28-3) is a high-purity analytical reference standard with the molecular formula C14H10O3S and a molecular weight of 258.29 g/mol.

The molecular framework of 6-Methoxy-2-(thiophen-2-ylmethylene)benzofuran-3(2H)-one (C14H10O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

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), 6-Methoxy-2-(thiophen-2-ylmethylene)benzofuran-3(2H)-one 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.
