Rocuronium Impurity 48 CAS 2562348-54-1 chemical structure

Description

Rocuronium Impurity 48 (CAS 2562348-54-1) is a certified pharmaceutical impurity reference standard with the molecular formula C18H26O and a molecular weight of 258.40 g/mol.

Rocuronium Impurity 48 (C18H26O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Rocuronium Impurity 48 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.
