Description
As a certified reference material (CRM), Lasmiditan Impurity 66 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.
CATO supplies Lasmiditan Impurity 66 (CAS CATO-C4X-247866), a pharmacopoeial impurity reference standard (molecular formula C13H17BrClN2OCl, MW 368.10 g/mol) used for the identification and quantification of trace impurities in APIs.
Lasmiditan Impurity 66 (C13H17BrClN2OCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
