Chemical Structure

Warfarin Impurity 13 CAS CATO-C4X-142913 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 310.34 g/mol gives Warfarin Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Warfarin Impurity 13 (CAS CATO-C4X-142913) is a certified pharmaceutical impurity reference standard with the molecular formula C19H18O4 and a molecular weight of 310.34 g/mol.

The molecular framework of Warfarin Impurity 13 (C19H18O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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.

As a certified reference material (CRM), Warfarin Impurity 13 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.
