Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 542.11 g/mol gives Barium 5-((3-carboxy-2-oxidonaphthalen-1-yl)diazenyl)-2-chlorobenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Barium 5-((3-carboxy-2-oxidonaphthalen-1-yl)diazenyl)-2-chlorobenzenesulfonate (CAS 76613-71-3), a certified reference material (molecular formula C17H9ClN2O6SBa, MW 542.11 g/mol) for analytical method development and quality control.
The molecular framework of Barium 5-((3-carboxy-2-oxidonaphthalen-1-yl)diazenyl)-2-chlorobenzenesulfonate (C17H9ClN2O6SBa) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
