Chemical Structure
Description
The molecular framework of Naltrexone impurity 55 (C24H25F6NO9S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a process- or degradation-related impurity, Naltrexone impurity 55 (CAS CATO-C4X-147555, C24H25F6NO9S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
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), Naltrexone impurity 55 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.
