Description

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.

CATO supplies 6966-45-6 A836593 trisodium; (3Z)-3-[(E)-[4-[bis(oxidanidyl)amino]-6-oxidanylidene-cyclohexa-2,4-dien-1-ylidene]hydrazinylidene]-4-oxidanylidene-naphthalene-1-sulfonate; chromium(3+); 3-[(4-nitro-2-oxidanidyl-phenyl)diazenyl]-4-oxidanidyl-naphthalene-1-sulfonate trisodium; chromium(3+); (3Z)-3-[(E)-[4-(dioxidoamino)-6-oxo-1-cyclohexa-2,4-dienylidene]hydrazinylidene]-4-oxo-1-naphthalenesulfonate; 3-(4-nitro-2-oxidophenyl)azo-4-oxido-1-naphthalenesulfonate (CAS 6966-45-6), a certified reference material (molecular formula C7H12Cl2O2S, MW 231.14 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 6966-45-6 A836593 trisodium; (3Z)-3-[(E)-[4-[bis(oxidanidyl)amino]-6-oxidanylidene-cyclohexa-2,4-dien-1-ylidene]hydrazinylidene]-4-oxidanylidene-naphthalene-1-sulfonate; chromium(3+); 3-[(4-nitro-2-oxidanidyl-phenyl)diazenyl]-4-oxidanidyl-naphthalene-1-sulfonate trisodium; chromium(3+); (3Z)-3-[(E)-[4-(dioxidoamino)-6-oxo-1-cyclohexa-2,4-dienylidene]hydrazinylidene]-4-oxo-1-naphthalenesulfonate; 3-(4-nitro-2-oxidophenyl)azo-4-oxido-1-naphthalenesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
