Netupitant Impurity 63 CAS CATO-C4X-122363

Description

The occurrence of Netupitant Impurity 63 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Netupitant Impurity 63 (CAS CATO-C4X-122363) is a certified pharmaceutical impurity reference standard with the molecular formula C12H10F6O2 and a molecular weight of 300.20 g/mol.

Based on its molecular formula C12H10F6O2, Netupitant Impurity 63 contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Netupitant Impurity 63 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.
