Vitamin K1 Impurity 20 CAS CATO-C4X-220720

Description

As a certified reference material (CRM), Vitamin K1 Impurity 20 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.

Vitamin K1 Impurity 20 (CAS CATO-C4X-220720) is a certified pharmaceutical impurity reference standard with the molecular formula C20H39Cl and a molecular weight of 314.98 g/mol.

Vitamin K1 Impurity 20 (C20H39Cl) contains chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
