Chemical Structure

Phytomenadione/Vitamin K1 Impurity 79 CAS CATO-C4X-220779 chemical structure

Description

Structurally, Phytomenadione/Vitamin K1 Impurity 79 (C13H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 216.23 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.

CATO supplies Phytomenadione/Vitamin K1 Impurity 79 (CAS CATO-C4X-220779), a pharmacopoeial impurity reference standard (molecular formula C13H12O3, MW 216.23 g/mol) used for the identification and quantification of trace impurities in APIs.

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.

CATO manufactures Phytomenadione/Vitamin K1 Impurity 79 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
