Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 241.15 g/mol gives Sodium 4-hydroxy-3-nitrobenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium 4-hydroxy-3-nitrobenzenesulfonate (CAS 6313-34-4), a certified reference material (molecular formula C6H4NO6SNa, MW 241.15 g/mol) for analytical method development and quality control.
The molecular framework of Sodium 4-hydroxy-3-nitrobenzenesulfonate (C6H4NO6SNa) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. 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.
As a certified reference material (CRM), Sodium 4-hydroxy-3-nitrobenzenesulfonate 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.
