Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 388.39 g/mol gives Iguratimod Impurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Iguratimod Impurity 40 (CAS 1179354-65-4) is a certified pharmaceutical impurity reference standard with the molecular formula C18H16N2O6S and a molecular weight of 388.39 g/mol.
Iguratimod Impurity 40 (C18H16N2O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Iguratimod Impurity 40 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.
