Chemical Structure

Sodium Valproate Impurity 42 CAS 258264-00-5 chemical structure

Description

CATO supplies Sodium Valproate Impurity 42 (CAS 258264-00-5), a pharmacopoeial impurity reference standard (molecular formula C11H20O4, MW 216.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C11H20O4, Sodium Valproate Impurity 42 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 216.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures Sodium Valproate Impurity 42 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
