Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Sodium4,4',4'',4'''-(ethene-1,1,2,2-tetrayl)tetrabenzenesulfonate (CAS 2116433-85-1), a certified reference material (molecular formula C26H20O12S4Na, MW 675.66 g/mol) for analytical method development and quality control.
The molecular framework of Sodium4,4',4'',4'''-(ethene-1,1,2,2-tetrayl)tetrabenzenesulfonate (C26H20O12S4Na) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
CATO manufactures Sodium4,4',4'',4'''-(ethene-1,1,2,2-tetrayl)tetrabenzenesulfonate 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.
