Chemical Structure

Phytomenadione/Vitamin K1 Impurity 129 CAS 1181-23-3（无手性） chemical structure

Description

The occurrence of Phytomenadione/Vitamin K1 Impurity 129 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Phytomenadione/Vitamin K1 Impurity 129 (CAS 1181-23-3（无手性）, C31H48O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Phytomenadione/Vitamin K1 Impurity 129 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 468.71 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 Phytomenadione/Vitamin K1 Impurity 129 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.
