Chemical Structure

1,4-Benzenedicarboxylic acid, polymer with decanedioic acid and 1,2-ethanediol CAS 25067-21-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Benzenedicarboxylic acid, polymer with decanedioic acid and 1,2-ethanediol.

1,4-Benzenedicarboxylic acid, polymer with decanedioic acid and 1,2-ethanediol (CAS 25067-21-4), molecular formula C10H18O4C8H6O4C2H6O2 and molecular weight 430.45 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H18O4C8H6O4C2H6O2, 1,4-Benzenedicarboxylic acid, polymer with decanedioic acid and 1,2-ethanediol contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 430.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 1,4-Benzenedicarboxylic acid, polymer with decanedioic acid and 1,2-ethanediol 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.
