ethyl 5,6-dimethoxy-1-benzothiophene-2-carboxylate CAS 1207537-68-5

Description

Compared with other compounds in its class, the molecular weight of 266.31 g/mol gives ethyl 5,6-dimethoxy-1-benzothiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

ethyl 5,6-dimethoxy-1-benzothiophene-2-carboxylate (CAS 1207537-68-5), molecular formula C13H14O4S and molecular weight 266.31 g/mol, is a CATO reference standard with documented purity and traceability.

ethyl 5,6-dimethoxy-1-benzothiophene-2-carboxylate (C13H14O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 5,6-dimethoxy-1-benzothiophene-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.
