Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1,3-Benzenedicarboxylic acid, 5-sulfo-, sodium salt , polymer with hexanedioic acid and 1,6-hexanediol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 532.49 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, 5-sulfo-, sodium salt , polymer with hexanedioic acid and 1,6-hexanediol (CAS 163794-90-9), molecular formula C8H5O7SC6H10O4C6H14O2Na and molecular weight 532.49 g/mol, is a CATO reference standard with documented purity and traceability.
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.
