Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 323.83 g/mol gives Oseltamivir EP Impurity C-d3 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Oseltamivir EP Impurity C-d3 HCl (CAS CATO-C4X-172032) is a certified pharmaceutical impurity reference standard with the molecular formula C14H21D3N2O4HCl and a molecular weight of 323.83 g/mol.
Structurally, Oseltamivir EP Impurity C-d3 HCl (C14H21D3N2O4HCl) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 323.83 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures Oseltamivir EP Impurity C-d3 HCl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
