Description
As a certified reference material (CRM), Perindopril EP Impurity B 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 Perindopril EP Impurity B (CAS 95153-31-4), a pharmacopoeial impurity reference standard (molecular formula C17H28N2O5, MW 340.41 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Perindopril EP Impurity B (C17H28N2O5) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
