Chemical Structure

Oseltamivir Impurity 145 CAS 2714884-77-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 254.32 g/mol gives Oseltamivir Impurity 145 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Oseltamivir Impurity 145 (CAS 2714884-77-0), a pharmacopoeial impurity reference standard (molecular formula C14H22O4, MW 254.32 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H22O4, Oseltamivir Impurity 145 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures Oseltamivir Impurity 145 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.
