Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Pitolisant Impurity 45 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 543.01 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).
Pitolisant Impurity 45 (CAS CATO-C4X-252045) is a certified pharmaceutical impurity reference standard with the molecular formula C29H42Cl2NO2Cl and a molecular weight of 543.01 g/mol.
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), Pitolisant Impurity 45 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.
