Menaquinone impurity 7 CAS 523-38-6

Description

Compared with other compounds in its class, the molecular weight of 717.12 g/mol gives Menaquinone impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Menaquinone impurity 7 (CAS 523-38-6) is a certified pharmaceutical impurity reference standard with the molecular formula C51H72O2 and a molecular weight of 717.12 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Menaquinone impurity 7 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 717.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 7 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.
