Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Regadenoson Impurity 58.
CATO supplies Regadenoson Impurity 58 (CAS CATO-C4X-198558), a pharmacopoeial impurity reference standard (molecular formula C22H25N7O9, MW 531.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Regadenoson Impurity 58 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 531.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Regadenoson Impurity 58 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.
