Chemical Structure
Description
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.
1,4-Benzenedicarboxylic acid, polymer with 1,2-ethanediol and nonanedioic acid (CAS 25609-72-7) is a high-purity analytical reference standard with the molecular formula C9H16O4C8H6O4C2H6O2 and a molecular weight of 416.42 g/mol.
1,4-Benzenedicarboxylic acid, polymer with 1,2-ethanediol and nonanedioic acid (C9H16O4C8H6O4C2H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
As a certified reference material (CRM), 1,4-Benzenedicarboxylic acid, polymer with 1,2-ethanediol and nonanedioic 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.
