Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 236.31 g/mol gives Oseltamivir Impurity 92 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Oseltamivir Impurity 92 (CAS 1151665-78-9), a pharmacopoeial impurity reference standard (molecular formula C14H20O3, MW 236.31 g/mol) used for the identification and quantification of trace impurities in APIs.
Oseltamivir Impurity 92 (C14H20O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 92 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.
