Chemical Structure

Sodium Valproate Impurity 7 CAS 110-59-8 chemical structure

Description

As a certified reference material (CRM), Sodium Valproate Impurity 7 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.

As a process- or degradation-related impurity, Sodium Valproate Impurity 7 (CAS 110-59-8, C5H9N) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrile group, Sodium Valproate Impurity 7 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 83.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
