Oseltamivir Impurity 135 CAS CATO-C4X-1720135

Description

The occurrence of Oseltamivir Impurity 135 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Oseltamivir Impurity 135 (CAS CATO-C4X-1720135), a pharmacopoeial impurity reference standard (molecular formula C14H22O7S, MW 334.39 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H22O7S, Oseltamivir Impurity 135 contains a sulfone group, 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 334.39 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).

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.

CATO manufactures Oseltamivir Impurity 135 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.
