1,3-Benzenedicarboxylic acid, polymer with 1,2-ethanediol, ethenylbenzene, 2,5-furandione and 1,2-propanediol CAS 67939-09-7 chemical structure

Description

1,3-Benzenedicarboxylic acid, polymer with 1,2-ethanediol, ethenylbenzene, 2,5-furandione and 1,2-propanediol (CAS 67939-09-7), molecular formula C8H6O4C8H8C4H2O3C3H8O2C2H6O2 and molecular weight 506.50 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,3-Benzenedicarboxylic acid, polymer with 1,2-ethanediol, ethenylbenzene, 2,5-furandione and 1,2-propanediol (C8H6O4C8H8C4H2O3C3H8O2C2H6O2) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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 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.

CATO manufactures 1,3-Benzenedicarboxylic acid, polymer with 1,2-ethanediol, ethenylbenzene, 2,5-furandione and 1,2-propanediol 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.
