Description
As a certified reference material (CRM), Rocuronium Impurity 19 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 Rocuronium Impurity 19 (CAS CATO-C4X-124219), a pharmacopoeial impurity reference standard (molecular formula C29H48N2O4, MW 488.70 g/mol) used for the identification and quantification of trace impurities in APIs.
Rocuronium Impurity 19 (C29H48N2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
