Chemical Structure

Valaciclovir EP Impurity G CAS 1122-58-3 chemical structure

Description

As a certified reference material (CRM), Valaciclovir EP Impurity G 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, Valaciclovir EP Impurity G (CAS 1122-58-3, C7H10N2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrile group, an aromatic ring system, Valaciclovir EP Impurity G is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 122.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
