Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,7-Disulfonaphthalene-1,4-dicarboxylic acid.
5,7-Disulfonaphthalene-1,4-dicarboxylic acid (CAS 1267804-17-0) is a high-purity analytical reference standard with the molecular formula C12H8O10S2 and a molecular weight of 376.32 g/mol.
The molecular framework of 5,7-Disulfonaphthalene-1,4-dicarboxylic acid (C12H8O10S2) is characterized by a carbohydrate-derived structure, a sulfone group. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 5,7-Disulfonaphthalene-1,4-dicarboxylic acid 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.
