Chemical Structure

Oseltamivir Impurity 170 CAS 122-51-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 148.20 g/mol gives Oseltamivir Impurity 170 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Oseltamivir Impurity 170 (CAS 122-51-0), a pharmacopoeial impurity reference standard (molecular formula C7H16O3, MW 148.20 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Oseltamivir Impurity 170 (C7H16O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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 170 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.
