Description
As a certified reference material (CRM), Rimegepant Impurity 125 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.
Rimegepant Impurity 125 (CAS CATO-C4X-2487125) is a certified pharmaceutical impurity reference standard with the molecular formula C25H36F2N2OSi and a molecular weight of 446.65 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Rimegepant Impurity 125 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 446.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
