Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 716.39 g/mol gives Dotinurad Impurity 51 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dotinurad Impurity 51 (CAS CATO-C4X-249451) is a certified pharmaceutical impurity reference standard with the molecular formula C28H18Cl4N2O8S2 and a molecular weight of 716.39 g/mol.
The molecular framework of Dotinurad Impurity 51 (C28H18Cl4N2O8S2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Dotinurad Impurity 51 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.
