Chemical Structure
Description
The occurrence of 1,3-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 4,4'-(1-methylethylidene)bis[phenol] is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 4,4'-(1-methylethylidene)bis[phenol] (CAS 26590-50-1) is a high-purity analytical reference standard with the molecular formula C15H16O2C8H6O4 and a molecular weight of 394.42 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 4,4'-(1-methylethylidene)bis[phenol] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1,3-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 4,4'-(1-methylethylidene)bis[phenol] 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.
