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 1,2-ethanediol, 2,5-furandione and 2,2'-oxybis[ethanol] (CAS 26795-76-6), molecular formula C8H6O4C4H10O3C4H2O3C2H6O2 and molecular weight 432.38 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Benzenedicarboxylic acid, polymer with 1,2-ethanediol, 2,5-furandione and 2,2'-oxybis[ethanol] is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.38 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
