Compared with other compounds in its class, the molecular weight of 859.78 g/mol gives Sodium 3,3'-((ethene-1,2-diylbis(3-sulfonato-4,1-phenylene))bis(diazene-2,1-diyl))bis(4-hydroxynaphthalene-1-sulfonate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium 3,3'-((ethene-1,2-diylbis(3-sulfonato-4,1-phenylene))bis(diazene-2,1-diyl))bis(4-hydroxynaphthalene-1-sulfonate) (CAS 6962-42-1), a certified reference material (molecular formula C34H20N4O14S4Na, MW 859.78 g/mol) for analytical method development and quality control.
The molecular framework of Sodium 3,3'-((ethene-1,2-diylbis(3-sulfonato-4,1-phenylene))bis(diazene-2,1-diyl))bis(4-hydroxynaphthalene-1-sulfonate) (C34H20N4O14S4Na) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Sodium 3,3'-((ethene-1,2-diylbis(3-sulfonato-4,1-phenylene))bis(diazene-2,1-diyl))bis(4-hydroxynaphthalene-1-sulfonate) 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.
