Rimegepant Impurity 71 CAS CATO-C4X-248771

Description

The occurrence of Rimegepant Impurity 71 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Rimegepant Impurity 71 (CAS CATO-C4X-248771) is a certified pharmaceutical impurity reference standard with the molecular formula C25H37FN2OSi and a molecular weight of 428.66 g/mol.

Rimegepant Impurity 71 (C25H37FN2OSi) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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.

As a certified reference material (CRM), Rimegepant Impurity 71 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.
