Ionone Impurity 3 CAS 14398-34-6

Description

Compared with other compounds in its class, the molecular weight of 208.30 g/mol gives Ionone Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ionone Impurity 3 (CAS 14398-34-6) is a certified pharmaceutical impurity reference standard with the molecular formula C13H20O2 and a molecular weight of 208.30 g/mol.

Structurally, Ionone Impurity 3 (C13H20O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 208.30 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), Ionone Impurity 3 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.
