Chemical Structure

Piracetam Impurity 45 CAS CATO-C4X-123545 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 156.14 g/mol gives Piracetam Impurity 45 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Piracetam Impurity 45 (CAS CATO-C4X-123545, C6H8N2O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Piracetam Impurity 45 (C6H8N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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), Piracetam Impurity 45 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.
