Chemical Structure
Description
The occurrence of Phytomenadione/Vitamin K1 Impurity 78 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.
Phytomenadione/Vitamin K1 Impurity 78 (CAS CATO-C4X-220778) is a certified pharmaceutical impurity reference standard with the molecular formula C35H52O4 and a molecular weight of 536.78 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Phytomenadione/Vitamin K1 Impurity 78 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 536.78 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.
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.
As a certified reference material (CRM), Phytomenadione/Vitamin K1 Impurity 78 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.
