Description
As a certified reference material (CRM), Rabeprazole Impurity 25 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 Rabeprazole Impurity 25 (CAS 1286104-27-5), a pharmacopoeial impurity reference standard (molecular formula C14H11N3O3, MW 269.26 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Rabeprazole Impurity 25 (C14H11N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 269.26 g/mol, it falls into the medium-molecular-weight range. 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.
