Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 673.11 g/mol gives Relugolix Impurity 186 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Relugolix Impurity 186 (CAS CATO-C4X-2429186) is a certified pharmaceutical impurity reference standard with the molecular formula C30H29ClF2N7O5S and a molecular weight of 673.11 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Relugolix Impurity 186 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 673.11 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.
As a certified reference material (CRM), Relugolix Impurity 186 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.
