Chemical Structure

Sodium Valproate EP Impurity C CAS 62391-99-5 chemical structure

Description

The occurrence of Sodium Valproate EP Impurity C 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.

Sodium Valproate EP Impurity C (CAS 62391-99-5) is a certified pharmaceutical impurity reference standard with the molecular formula C8H16O2 and a molecular weight of 144.21 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Sodium Valproate EP Impurity C is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

As a certified reference material (CRM), Sodium Valproate EP Impurity C 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.
