Opicapone impurity 17 CAS CATO-C4X-240417

Description

Compared with other compounds in its class, the molecular weight of 263.21 g/mol gives Opicapone impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Opicapone impurity 17 (CAS CATO-C4X-240417) is a certified pharmaceutical impurity reference standard with the molecular formula C11H9N3O5 and a molecular weight of 263.21 g/mol.

Structurally, Opicapone impurity 17 (C11H9N3O5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 263.21 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), Opicapone impurity 17 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.
