Description
As a certified reference material (CRM), Trelagliptin Impurity 68 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 Trelagliptin Impurity 68 (CAS CATO-C4X-104668), a pharmacopoeial impurity reference standard (molecular formula C20H19F4N5O3, MW 453.39 g/mol) used for the identification and quantification of trace impurities in APIs.
Trelagliptin Impurity 68 (C20H19F4N5O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
