Description

Compared with other compounds in its class, the molecular weight of 402.39 g/mol gives 2,5-Bis(2-(2-methoxyethoxy)ethoxy)terephthalic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,5-Bis(2-(2-methoxyethoxy)ethoxy)terephthalic acid (CAS 116160-23-7) is a high-purity analytical reference standard with the molecular formula C18H26O10 and a molecular weight of 402.39 g/mol.

The molecular framework of 2,5-Bis(2-(2-methoxyethoxy)ethoxy)terephthalic acid (C18H26O10) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
