Rasagiline Impurity 67 CAS CATO-C4X-191367 chemical structure

Description

As a certified reference material (CRM), Rasagiline Impurity 67 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 67 (CAS CATO-C4X-191367) is a certified pharmaceutical impurity reference standard with the molecular formula C18H16O2 and a molecular weight of 264.32 g/mol.

Rasagiline Impurity 67 (C18H16O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
