Chemical Structure

Sodium Valproate Impurity 41 CAS CATO-C4X-116641 chemical structure

Description

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.

CATO supplies Sodium Valproate Impurity 41 (CAS CATO-C4X-116641), a pharmacopoeial impurity reference standard (molecular formula C14H26O4, MW 258.35 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Sodium Valproate Impurity 41 (C14H26O4) is characterized by a carboxylic acid group, 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.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
