Chemical Structure

Phytomenadione/Vitamin K1 Impurity 117 CAS CATO-C4X-2207117 chemical structure

Description

As a certified reference material (CRM), Phytomenadione/Vitamin K1 Impurity 117 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 Phytomenadione/Vitamin K1 Impurity 117 (CAS CATO-C4X-2207117), a pharmacopoeial impurity reference standard (molecular formula C20H38O, MW 294.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Phytomenadione/Vitamin K1 Impurity 117 (C20H38O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 294.52 g/mol, it falls into the medium-molecular-weight range. 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.
