Chemical Structure
Description
The occurrence of Atogepant Impurity 30 is closely related to a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Atogepant Impurity 30 (CAS 52011-50-4) is a certified pharmaceutical impurity reference standard with the molecular formula C4H6Br2O and a molecular weight of 229.90 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, Atogepant Impurity 30 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Atogepant Impurity 30 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.
