Chemical Structure
Description
Phytomenadione/Vitamin K1 Impurity 87 (CAS CATO-C4X-220787) is a certified pharmaceutical impurity reference standard with the molecular formula C31H46O3 and a molecular weight of 466.70 g/mol.
Based on its molecular formula C31H46O3, Phytomenadione/Vitamin K1 Impurity 87 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 466.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
