1,3-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 2,2,4-trimethyl-1,3-pentanediol CAS 65970-31-2

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.

1,3-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 2,2,4-trimethyl-1,3-pentanediol (CAS 65970-31-2), molecular formula C8H6O4C8H18O2 and molecular weight 312.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H6O4C8H18O2, 1,3-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid and 2,2,4-trimethyl-1,3-pentanediol contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 312.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
