Chemical Structure
Description
Phytomenadione/Vitamin K1 Impurity 83 (CAS CATO-C4X-220783) is a certified pharmaceutical impurity reference standard with the molecular formula C31H48O5 and a molecular weight of 500.71 g/mol.
Based on its molecular formula C31H48O5, Phytomenadione/Vitamin K1 Impurity 83 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 500.71 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.
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.
