Chemical Structure
Description
As a certified reference material (CRM), Phytomenadione/Vitamin K1 Impurity 92 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Phytomenadione/Vitamin K1 Impurity 92 (CAS CATO-C4X-220792) is a certified pharmaceutical impurity reference standard with the molecular formula C31H46O2 and a molecular weight of 450.70 g/mol.
The molecular framework of Phytomenadione/Vitamin K1 Impurity 92 (C31H46O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
