Vitamin K1 Impurity 42 CAS 326475-12-1

Description

Compared with other compounds in its class, the molecular weight of 278.52 g/mol gives Vitamin K1 Impurity 42 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Vitamin K1 Impurity 42 (CAS 326475-12-1) is a certified pharmaceutical impurity reference standard with the molecular formula C20H38 and a molecular weight of 278.52 g/mol.

Vitamin K1 Impurity 42 (C20H38) contains an organic framework. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Vitamin K1 Impurity 42 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.
