Chemical Structure
Description
As a certified reference material (CRM), Galanthamine Impurity 45 (4aR,6R,8aS) 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, Galanthamine Impurity 45 (4aR,6R,8aS) (CAS CATO-C4X-143545, C24H25NO4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Galanthamine Impurity 45 (4aR,6R,8aS) (C24H25NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
