Chemical Structure

Valproate Impurity 49 CAS 40239-27-8 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 Valproate Impurity 49 (CAS 40239-27-8), a pharmacopoeial impurity reference standard (molecular formula C9H18O, MW 142.24 g/mol) used for the identification and quantification of trace impurities in APIs.

Valproate Impurity 49 (C9H18O) contains a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
