Eperisone Impurity 46 HCl CAS CATO-C4X-227946

Description

Compared with other compounds in its class, the molecular weight of 267.80 g/mol gives Eperisone Impurity 46 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Eperisone Impurity 46 HCl (CAS CATO-C4X-227946) is a certified pharmaceutical impurity reference standard with the molecular formula C15H21NOHCl and a molecular weight of 267.80 g/mol.

The molecular framework of Eperisone Impurity 46 HCl (C15H21NOHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

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.
