Description
As a certified reference material (CRM), Elagolix Impurity 78 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.
Elagolix Impurity 78 (CAS CATO-C4X-206878) is a certified pharmaceutical impurity reference standard with the molecular formula C8H7F4NHCl and a molecular weight of 229.60 g/mol.
Owing to a nitrile group, fluorine/chlorine substitution, Elagolix Impurity 78 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.60 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
