Ceritinib Impurity 88 CAS 1823331-67-4 chemical structure

Description

Ceritinib Impurity 88 (CAS 1823331-67-4) is a certified pharmaceutical impurity reference standard with the molecular formula C12H19NS and a molecular weight of 209.35 g/mol.

Structurally, Ceritinib Impurity 88 (C12H19NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 209.35 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 Ceritinib Impurity 88 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.
