Menaquinone impurity 14 CAS 69729-17-5 chemical structure

Description

CATO manufactures Menaquinone impurity 14 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.

Menaquinone impurity 14 (CAS 69729-17-5) is a certified pharmaceutical impurity reference standard with the molecular formula C18H38O and a molecular weight of 270.49 g/mol.

The molecular framework of Menaquinone impurity 14 (C18H38O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
