Chemical Structure
Description
As a certified reference material (CRM), Vitamin K1 Impurity 11 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.
CATO supplies Vitamin K1 Impurity 11 (CAS CATO-C4X-220711), a pharmacopoeial impurity reference standard (molecular formula C31H46O2, MW 450.70 g/mol) used for the identification and quantification of trace impurities in APIs.
Vitamin K1 Impurity 11 (C31H46O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
