Chemical Structure

1,3-Benzenedicarboxylic acid, polymer with hexanedioic acid and 2,2,4-trimethyl-1,3-pentanediol, 3-oxobutanoate CAS 142982-23-8 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

1,3-Benzenedicarboxylic acid, polymer with hexanedioic acid and 2,2,4-trimethyl-1,3-pentanediol, 3-oxobutanoate (CAS 142982-23-8), molecular formula C12H22O4C8H6O4C6H10O4 and molecular weight 542.58 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1,3-Benzenedicarboxylic acid, polymer with hexanedioic acid and 2,2,4-trimethyl-1,3-pentanediol, 3-oxobutanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 542.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
