Valproic Acid Methyl Ester CAS 22632-59-3 chemical structure

Description

CATO manufactures Valproic Acid Methyl Ester 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.

Valproic Acid Methyl Ester (CAS 22632-59-3), molecular formula C9H18O2 and molecular weight 158.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Valproic Acid Methyl Ester (C9H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
