Chemical Structure
Description
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1,3-Benzenedicarboxylic acid, polymer with 1,3-benzenediamine and 2,4-diaminobenzenesulfonic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.48 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).
1,3-Benzenedicarboxylic acid, polymer with 1,3-benzenediamine and 2,4-diaminobenzenesulfonic acid (CAS 69847-62-7) is a high-purity analytical reference standard with the molecular formula C6H8N2O3SC8H6O4C6H8N2 and a molecular weight of 462.48 g/mol.
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.
