Ceritinib Impurity 34 CAS CATO-C4X-104834

Description

Compared with other compounds in its class, the molecular weight of 413.36 g/mol gives Ceritinib Impurity 34 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ceritinib Impurity 34 (CAS CATO-C4X-104834), a pharmacopoeial impurity reference standard (molecular formula C22H25N2OBr, MW 413.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ceritinib Impurity 34 (C22H25N2OBr) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 413.36 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Ceritinib Impurity 34 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.
