Description
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.
Loxoprofen Impurity 110 (CAS CATO-C4X-1488110) is a certified pharmaceutical impurity reference standard with the molecular formula C30H34O5 and a molecular weight of 474.59 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, Loxoprofen Impurity 110 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 474.59 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).
As a certified reference material (CRM), Loxoprofen Impurity 110 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.
