Chemical Structure

Valproate impurity 88 CAS CATO-C4X-116688 chemical structure

Description

The occurrence of Valproate impurity 88 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Valproate impurity 88 (CAS CATO-C4X-116688) is a certified pharmaceutical impurity reference standard with the molecular formula C8H16O3 and a molecular weight of 160.21 g/mol.

Based on its molecular formula C8H16O3, Valproate impurity 88 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 160.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

As a certified reference material (CRM), Valproate impurity 88 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
