Rasagiline Impurity 33 CAS CATO-C4X-191333 chemical structure

Description

As a certified reference material (CRM), Rasagiline Impurity 33 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.

Rasagiline Impurity 33 (CAS CATO-C4X-191333) is a certified pharmaceutical impurity reference standard with the molecular formula C18H18N2O and a molecular weight of 278.35 g/mol.

Rasagiline Impurity 33 (C18H18N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
