58428-97-0 AR-1I2673 copper(2+) sodium 4-oxido-7-[({5-oxido-6-[(e)-(2-oxido-5-sulfonatophenyl)diazenyl]-7-sulfonatonaphthalen-2-yl}carbamoyl)amino]-3-[(e)-(2-oxido-5-sulfonatophenyl)diazenyl]naphthalene-2-sulfonate(2:4:1) CAS 58428-97-0

Description

Compared with other compounds in its class, the molecular weight of 334.49 g/mol gives 58428-97-0 AR-1I2673 copper(2+) sodium 4-oxido-7-[({5-oxido-6-[(e)-(2-oxido-5-sulfonatophenyl)diazenyl]-7-sulfonatonaphthalen-2-yl}carbamoyl)amino]-3-[(e)-(2-oxido-5-sulfonatophenyl)diazenyl]naphthalene-2-sulfonate(2:4:1) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

58428-97-0 AR-1I2673 copper(2+) sodium 4-oxido-7-[({5-oxido-6-[(e)-(2-oxido-5-sulfonatophenyl)diazenyl]-7-sulfonatonaphthalen-2-yl}carbamoyl)amino]-3-[(e)-(2-oxido-5-sulfonatophenyl)diazenyl]naphthalene-2-sulfonate(2:4:1) (CAS 58428-97-0), molecular formula C15H26O4S2 and molecular weight 334.49 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 58428-97-0 AR-1I2673 copper(2+) sodium 4-oxido-7-[({5-oxido-6-[(e)-(2-oxido-5-sulfonatophenyl)diazenyl]-7-sulfonatonaphthalen-2-yl}carbamoyl)amino]-3-[(e)-(2-oxido-5-sulfonatophenyl)diazenyl]naphthalene-2-sulfonate(2:4:1) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
