Chemical Structure

4,4'-((2,5-Dimethoxy-1,4-phenylene)bis(ethene-2,1-diyl))dibenzoic acid CAS 67546-17-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 430.45 g/mol gives 4,4'-((2,5-Dimethoxy-1,4-phenylene)bis(ethene-2,1-diyl))dibenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4'-((2,5-Dimethoxy-1,4-phenylene)bis(ethene-2,1-diyl))dibenzoic acid (CAS 67546-17-2), molecular formula C26H22O6 and molecular weight 430.45 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 4,4'-((2,5-Dimethoxy-1,4-phenylene)bis(ethene-2,1-diyl))dibenzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 430.45 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), 4,4'-((2,5-Dimethoxy-1,4-phenylene)bis(ethene-2,1-diyl))dibenzoic acid 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.
