Chemical Structure
Description
As a certified reference material (CRM), N,N'-((ethane-1,2-diylbis(oxy))bis(ethane-2,1-diyl))bis(4-methylbenzenesulfonamide) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
N,N'-((ethane-1,2-diylbis(oxy))bis(ethane-2,1-diyl))bis(4-methylbenzenesulfonamide) (CAS 59945-35-6), molecular formula C20H28N2O6S2 and molecular weight 456.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N,N'-((ethane-1,2-diylbis(oxy))bis(ethane-2,1-diyl))bis(4-methylbenzenesulfonamide) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 456.58 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.
