Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 146.19 g/mol gives Warfarin EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Warfarin EP Impurity C (CAS 1896-62-4), a pharmacopoeial impurity reference standard (molecular formula C10H10O, MW 146.19 g/mol) used for the identification and quantification of trace impurities in APIs.
Warfarin EP Impurity C (C10H10O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
