Bis(Bis[(1,2-benzisothiazol-3(2H)-one-κN2) 1,1-dioxidato]bis(1H-imidazole-5-ethanamine-κN1,κN5)copper)bis(saccharinato)copper(II) (CAS 937810-83-8), molecular formula C24H26CuN8O6S2 and molecular weight 650.19 g/mol, is a CATO reference standard with documented purity and traceability.
Bis(Bis[(1,2-benzisothiazol-3(2H)-one-κN2) 1,1-dioxidato]bis(1H-imidazole-5-ethanamine-κN1,κN5)copper)bis(saccharinato)copper(II) (C24H26CuN8O6S2) contains a flavonoid core, 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. 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.
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.
