Based on its molecular formula C6H10O4, Sodium Valproate Impurity 19 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 146.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
CATO supplies Sodium Valproate Impurity 19 (CAS 616-62-6), a pharmacopoeial impurity reference standard (molecular formula C6H10O4, MW 146.14 g/mol) used for the identification and quantification of trace impurities in APIs.
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.
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.
