Chemical Structure

Lifitegrast impurity 92 CAS CATO-C4X-240992 chemical structure

Description

CATO supplies Lifitegrast impurity 92 (CAS CATO-C4X-240992), a pharmacopoeial impurity reference standard (molecular formula C20H24N2O7S2, MW 468.54 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C20H24N2O7S2, Lifitegrast impurity 92 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 468.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Lifitegrast impurity 92 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.
