Description
Mometasone Impurity 30 (CAS CATO-C4X-170430) is a certified pharmaceutical impurity reference standard with the molecular formula N/A and a molecular weight of 504.38 g/mol.
Mometasone Impurity 30 is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
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), Mometasone Impurity 30 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.
