Ziprasidone Impurity 22 CAS 223586-82-1

Description

Compared with other compounds in its class, the molecular weight of 352.48 g/mol gives Ziprasidone Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ziprasidone Impurity 22 (CAS 223586-82-1), a pharmacopoeial impurity reference standard (molecular formula C18H16N4S2, MW 352.48 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Ziprasidone Impurity 22 (C18H16N4S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Ziprasidone Impurity 22 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.
