Description
68133-07-3 Hexanedioic acid, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,3-isobenzofurandione and 1,1'-oxybis(2-propanol) (CAS 68133-07-3) is a high-purity analytical reference standard with the molecular formula C8H4O3C6H10O4C6H14O3 and a molecular weight of 428.43 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 68133-07-3 Hexanedioic acid, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,3-isobenzofurandione and 1,1'-oxybis(2-propanol) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
