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-dimethyl 1,4-cyclohexanedicarboxylate, 2,2-dimethyl-1,3-propanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,6-hexanediol and nonanedioic acid (CAS 89911-11-5) is a high-purity analytical reference standard with the molecular formula C10H16O4C9H16O4C8H6O4C6H14O3C6H14O2C5H12O2 and a molecular weight of 911.09 g/mol.

Structurally, 1,3-Benzenedicarboxylic acid, polymer with 1,4-dimethyl 1,4-cyclohexanedicarboxylate, 2,2-dimethyl-1,3-propanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,6-hexanediol and nonanedioic acid (C10H16O4C9H16O4C8H6O4C6H14O3C6H14O2C5H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 911.09 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 1,3-Benzenedicarboxylic acid, polymer with 1,4-dimethyl 1,4-cyclohexanedicarboxylate, 2,2-dimethyl-1,3-propanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,6-hexanediol and nonanedioic acid 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.
