Chemical Structure

Cenobamate Impurity 33 CAS CATO-C4X-241633 chemical structure

Description

The occurrence of Cenobamate Impurity 33 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Cenobamate Impurity 33 (CAS CATO-C4X-241633), a pharmacopoeial impurity reference standard (molecular formula C9H7ClN4, MW 206.63 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Cenobamate Impurity 33 (C9H7ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 206.63 g/mol, it falls into the medium-molecular-weight range. 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 Cenobamate Impurity 33 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.
