Description
As a certified reference material (CRM), Doxylamine Hydrogen Succinate EP Impurity A 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, Doxylamine Hydrogen Succinate EP Impurity A (CAS CATO-C4X-178921, C17H22N2O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Doxylamine Hydrogen Succinate EP Impurity A is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 270.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
