Phytomenadione/Vitamin K1 Impurity 86 CAS CATO-C4X-220786

Description

The occurrence of Phytomenadione/Vitamin K1 Impurity 86 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Phytomenadione/Vitamin K1 Impurity 86 (CAS CATO-C4X-220786) is a certified pharmaceutical impurity reference standard with the molecular formula C31H48O4 and a molecular weight of 484.71 g/mol.

The molecular framework of Phytomenadione/Vitamin K1 Impurity 86 (C31H48O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
