CATO supplies Sodium 6,6'-((4,8-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-1,5-diyl)bis(azanediyl))bis(3-methylbenzenesulfonate) (CAS 3209-30-1), a certified reference material (molecular formula C28H20N2O10S2Na, MW 631.58 g/mol) for analytical method development and quality control.
Sodium 6,6'-((4,8-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-1,5-diyl)bis(azanediyl))bis(3-methylbenzenesulfonate) (C28H20N2O10S2Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
