Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 223.70 g/mol gives Rasagiline impurity 56 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Rasagiline impurity 56 (CAS CATO-C4X-191356) is a certified pharmaceutical impurity reference standard with the molecular formula C12H13NOHCl and a molecular weight of 223.70 g/mol.
Structurally, Rasagiline impurity 56 (C12H13NOHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 223.70 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), Rasagiline impurity 56 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.
