Chemical Structure
Description
As a certified reference material (CRM), Dronedarone Impurity 57 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 Dronedarone Impurity 57 (CAS 98873-72-4), a pharmacopoeial impurity reference standard (molecular formula C17H13NO5, MW 311.29 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Dronedarone Impurity 57 (C17H13NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 311.29 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
