Tofacitinib Impurity 66 CAS 477600-69-4

Description

Compared with other compounds in its class, the molecular weight of 218.34 g/mol gives Tofacitinib Impurity 66 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Tofacitinib Impurity 66 (CAS 477600-69-4), a pharmacopoeial impurity reference standard (molecular formula C14H22N2, MW 218.34 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Tofacitinib Impurity 66 (C14H22N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 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).

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 Tofacitinib Impurity 66 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.
