Menaquinone impurity 17 CAS 62796-50-3

Description

The occurrence of Menaquinone impurity 17 is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Menaquinone impurity 17 (CAS 62796-50-3), a pharmacopoeial impurity reference standard (molecular formula C20H38O, MW 294.52 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Menaquinone impurity 17 (C20H38O) 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.

CATO manufactures Menaquinone impurity 17 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.
