Chemical Structure
Description
As a certified reference material (CRM), Oseltamivir Impurity 286 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.
Oseltamivir Impurity 286 (CAS CATO-C4X-1720286) is a certified pharmaceutical impurity reference standard with the molecular formula C11H16O4 and a molecular weight of 212.24 g/mol.
The molecular framework of Oseltamivir Impurity 286 (C11H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
