Chemical Structure
Description
CATO supplies Fluvoxamine Impurity 156 (CAS CATO-C4X-195156), a pharmacopoeial impurity reference standard (molecular formula C17H24ClF3N2O2HCl, MW 417.29 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Fluvoxamine Impurity 156 (C17H24ClF3N2O2HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 417.29 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), Fluvoxamine Impurity 156 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.
