The occurrence of 1,3-Benzenedicarboxylic acid, polymer with (2E)-2-butenedioic acid and 1,2-propanediol is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,3-Benzenedicarboxylic acid, polymer with (2E)-2-butenedioic acid and 1,2-propanediol (CAS 26249-22-9), a certified reference material (molecular formula C8H6O4C4H4O4C3H8O2, MW 358.30 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Benzenedicarboxylic acid, polymer with (2E)-2-butenedioic acid and 1,2-propanediol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.30 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
