Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 261.23 g/mol gives Sulfisozole sodium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sulfisozole sodium (CAS 79921-43-0), a certified reference material (molecular formula C9H8N3NaO3S, MW 261.23 g/mol) for analytical method development and quality control.
The molecular framework of Sulfisozole sodium (C9H8N3NaO3S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Sulfisozole sodium under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
