Chemical Structure
Description
As a certified reference material (CRM), Betamethasone Impurity 76 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 Betamethasone Impurity 76 (CAS 5534-01-0), a pharmacopoeial impurity reference standard (molecular formula N/A, MW 489.55 g/mol) used for the identification and quantification of trace impurities in APIs.
Betamethasone Impurity 76 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.
