Chemical Structure

Phytomenadione/Vitamin K1 Impurity 133 CAS 854039-21-7 chemical structure

Description

The occurrence of Phytomenadione/Vitamin K1 Impurity 133 is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Phytomenadione/Vitamin K1 Impurity 133 (CAS 854039-21-7) is a certified pharmaceutical impurity reference standard with the molecular formula C20H40O and a molecular weight of 296.53 g/mol.

Structurally, Phytomenadione/Vitamin K1 Impurity 133 (C20H40O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 296.53 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.

CATO manufactures Phytomenadione/Vitamin K1 Impurity 133 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.
