Menaquinone impurity 26 CAS CATO-C4X-207626 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 460.65 g/mol gives Menaquinone impurity 26 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Menaquinone impurity 26 (CAS CATO-C4X-207626) is a certified pharmaceutical impurity reference standard with the molecular formula C31H40O3 and a molecular weight of 460.65 g/mol.

Based on its molecular formula C31H40O3, Menaquinone impurity 26 contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 460.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Menaquinone impurity 26 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.
