Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 331.33 g/mol gives Rizatriptan Impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Rizatriptan Impurity 29 (CAS CATO-C4X-175229), a pharmacopoeial impurity reference standard (molecular formula C13H15N5C2H2O4, MW 331.33 g/mol) used for the identification and quantification of trace impurities in APIs.
Rizatriptan Impurity 29 (C13H15N5C2H2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Rizatriptan Impurity 29 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.
