Chemical Structure

2,4-Bis(4-methoxyphenyl)thiophene CAS 62497-30-7 chemical structure

Description

2,4-Bis(4-methoxyphenyl)thiophene (CAS 62497-30-7) is a high-purity analytical reference standard with the molecular formula C18H16O2S and a molecular weight of 296.38 g/mol.

The molecular framework of 2,4-Bis(4-methoxyphenyl)thiophene (C18H16O2S) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage. 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 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), 2,4-Bis(4-methoxyphenyl)thiophene 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.
