Chemical Structure

Levetiracetam Impurity 35 CAS 2259329-89-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 241.11 g/mol gives Levetiracetam Impurity 35 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Levetiracetam Impurity 35 (CAS 2259329-89-8, C8H14Cl2N2O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Levetiracetam Impurity 35 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 241.11 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.

As a certified reference material (CRM), Levetiracetam Impurity 35 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.
