Chemical Structure

Abrocitinib Impurity 55 CAS 252722-30-8 chemical structure

Description

Structurally, Abrocitinib Impurity 55 (C13H18N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 230.31 g/mol, it falls into the medium-molecular-weight range. 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).

As a process- or degradation-related impurity, Abrocitinib Impurity 55 (CAS 252722-30-8, C13H18N4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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 Abrocitinib Impurity 55 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.
