Oseltamivir Impurity 185 CAS CATO-C4X-1720185

Description

The occurrence of Oseltamivir Impurity 185 is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Oseltamivir Impurity 185 (CAS CATO-C4X-1720185) is a certified pharmaceutical impurity reference standard with the molecular formula C18H34N2O3 and a molecular weight of 326.47 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Oseltamivir Impurity 185 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.47 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.

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 185 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.
