Chemical Structure
Description
As a process- or degradation-related impurity, Lenalidomide Impurity 42 (CAS CATO-C4X-190342, C26H24N6O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
The molecular framework of Lenalidomide Impurity 42 (C26H24N6O6) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. 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), Lenalidomide Impurity 42 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.
