Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 593.74 g/mol gives Almotriptan Impurity 16 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Almotriptan Impurity 16 (CAS CATO-C4X-153816) is a certified pharmaceutical impurity reference standard with the molecular formula C30H39N7O4S and a molecular weight of 593.74 g/mol.
Almotriptan Impurity 16 (C30H39N7O4S) contains a steroid core, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Almotriptan Impurity 16 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.
