CATO supplies 1,4-Benzenedipentanoic acid, 2,5-dihydroxy-.delta.1,.delta.1,.delta.4,.delta.4-tetramethyl-, 1,4-dihexyl ester (CAS 85238-64-8), a certified reference material (molecular formula C32H54O6, MW 534.77 g/mol) for analytical method development and quality control.

Structurally, 1,4-Benzenedipentanoic acid, 2,5-dihydroxy-.delta.1,.delta.1,.delta.4,.delta.4-tetramethyl-, 1,4-dihexyl ester (C32H54O6) 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 534.77 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.

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.
