Chemical Structure

Oseltamivir Impurity 188 CAS CATO-C4X-1720188 chemical structure

Description

As a process- or degradation-related impurity, Oseltamivir Impurity 188 (CAS CATO-C4X-1720188, C14H24O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Oseltamivir Impurity 188 (C14H24O5) contains a carboxylic acid 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), Oseltamivir Impurity 188 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.
