Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 447.38 g/mol gives Sodium 2-hydroxy-5-((4-((4-sulfonatophenyl)diazenyl)phenyl)diazenyl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sodium 2-hydroxy-5-((4-((4-sulfonatophenyl)diazenyl)phenyl)diazenyl)benzoate (CAS 3564-27-0), molecular formula C19H12N4O6SNa and molecular weight 447.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Sodium 2-hydroxy-5-((4-((4-sulfonatophenyl)diazenyl)phenyl)diazenyl)benzoate (C19H12N4O6SNa) is characterized by a flavonoid core, 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. 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.
