Chemical Structure
Description
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 supplies Iguratimod Impurity 33 HCl (CAS CATO-C4X-182633), a pharmacopoeial impurity reference standard (molecular formula C15H12N2O3HCl, MW 304.73 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C15H12N2O3HCl, Iguratimod Impurity 33 HCl contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 304.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Iguratimod Impurity 33 HCl 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.
