Chemical Structure

Ceritinib Impurity 79 CAS CATO-C4X-104879 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 285.79 g/mol gives Ceritinib Impurity 79 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ceritinib Impurity 79 (CAS CATO-C4X-104879), a pharmacopoeial impurity reference standard (molecular formula C12H16ClN3OS, MW 285.79 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Ceritinib Impurity 79 (C12H16ClN3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
