Chemical Structure

1,2-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 1,4-butanediol CAS 68966-59-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 256.25 g/mol gives 1,2-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 1,4-butanediol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,2-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 1,4-butanediol (CAS 68966-59-6), a certified reference material (molecular formula C8H6O4C4H10O2, MW 256.25 g/mol) for analytical method development and quality control.

The molecular framework of 1,2-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 1,4-butanediol (C8H6O4C4H10O2) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 1,2-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 1,4-butanediol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
