Valproate Impurity 36 CAS 6065-62-9 chemical structure

Description

Valproate Impurity 36 (CAS 6065-62-9) is a certified pharmaceutical impurity reference standard with the molecular formula C12H22O4 and a molecular weight of 230.30 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Valproate Impurity 36 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Impurity 36 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.
