Chemical Structure
Description
1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 1,6-dimethyl hexanedioate and 1,2-ethanediol (C10H10O4C8H14O4C2H6O2) 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).
1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 1,6-dimethyl hexanedioate and 1,2-ethanediol (CAS 42342-18-7) is a high-purity analytical reference standard with the molecular formula C10H10O4C8H14O4C2H6O2 and a molecular weight of 430.45 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 1,6-dimethyl hexanedioate 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.
