Chemical Structure

Phytomenadione/Vitamin K1 Impurity 126 CAS CATO-C4X-2207126 chemical structure

Description

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.

As a process- or degradation-related impurity, Phytomenadione/Vitamin K1 Impurity 126 (CAS CATO-C4X-2207126, C40H74C20H38C20H38) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an aromatic ring system, Phytomenadione/Vitamin K1 Impurity 126 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1112.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
