Abrocitinib Impurity 29 CAS 2204276-97-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Abrocitinib Impurity 29.

CATO supplies Abrocitinib Impurity 29 (CAS 2204276-97-9), a pharmacopoeial impurity reference standard (molecular formula C13H19N5O2S, MW 309.39 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Abrocitinib Impurity 29 (C13H19N5O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.

As a certified reference material (CRM), Abrocitinib Impurity 29 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
