Chemical Structure
Description
As a certified reference material (CRM), Iguratimod Impurity 15 HCl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Iguratimod Impurity 15 HCl (CAS 149436-41-9), a pharmacopoeial impurity reference standard (molecular formula C16H18N2O5SHCl, MW 386.85 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Iguratimod Impurity 15 HCl (C16H18N2O5SHCl) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 386.85 g/mol, it falls into the moderately-high-molecular-weight range. 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.
