Description
As a certified reference material (CRM), Pantoprazole EP Impurity D and F（USP Impurity D and F） 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 Pantoprazole EP Impurity D and F（USP Impurity D and F） (CAS CATO-C4X-139910), a pharmacopoeial impurity reference standard (molecular formula C17H17F2N3O4S, MW 397.40 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Pantoprazole EP Impurity D and F（USP Impurity D and F） (C17H17F2N3O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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.
