Chemical Structure
Description
The occurrence of Valproate EP Impurity J is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Valproate EP Impurity J (CAS 5340-48-7), a pharmacopoeial impurity reference standard (molecular formula C11H21N, MW 167.29 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Valproate EP Impurity J (C11H21N) is characterized by a nitrile group. 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.
CATO manufactures Valproate EP Impurity J 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.
