Description

Compared with other compounds in its class, the molecular weight of 236.29 g/mol gives 1-(5,6-Dimethoxybenzo[b]thiophen-2-yl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(5,6-Dimethoxybenzo[b]thiophen-2-yl)ethan-1-one (CAS 108952-49-4), molecular formula C12H12O3S and molecular weight 236.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1-(5,6-Dimethoxybenzo[b]thiophen-2-yl)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1-(5,6-Dimethoxybenzo[b]thiophen-2-yl)ethan-1-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.
