Description
As a certified reference material (CRM), Olmesartan Impurity 52 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.
As a process- or degradation-related impurity, Olmesartan Impurity 52 (CAS 1040405-56-8, C49H46N6O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Olmesartan Impurity 52 (C49H46N6O6) contains a nitrogen-containing heterocyclic scaffold, 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.
