Chemical Structure
Description
The occurrence of Vitamin K1 Impurity 41 is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Vitamin K1 Impurity 41 (CAS 1778736-16-5) is a certified pharmaceutical impurity reference standard with the molecular formula C20H38 and a molecular weight of 278.52 g/mol.
Vitamin K1 Impurity 41 (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.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Vitamin K1 Impurity 41 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.
