Chemical Structure

Oseltamivir Impurity 110 CAS CATO-C4X-1720110 chemical structure

Description

The occurrence of Oseltamivir Impurity 110 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Oseltamivir Impurity 110 (CAS CATO-C4X-1720110), a pharmacopoeial impurity reference standard (molecular formula C13H18N4O5, MW 310.31 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Oseltamivir Impurity 110 (C13H18N4O5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
