Description
Vilanterol Impurity 25 L-Tartrate (CAS CATO-C4X-193525) is a certified pharmaceutical impurity reference standard with the molecular formula C30H45Cl2NO6C5H8O5 and a molecular weight of 734.71 g/mol.
Vilanterol Impurity 25 L-Tartrate (C30H45Cl2NO6C5H8O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), Vilanterol Impurity 25 L-Tartrate 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.
