Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 553.70 g/mol gives Atrasentan Impurity 116 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Atrasentan Impurity 116 (CAS 220584-55-4) is a certified pharmaceutical impurity reference standard with the molecular formula C31H43N3O6 and a molecular weight of 553.70 g/mol.
Based on its molecular formula C31H43N3O6, Atrasentan Impurity 116 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 553.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Atrasentan Impurity 116 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.
