Chemical Structure

Olanzapine Impurity 28 CAS CATO-C4X-117828 chemical structure

Description

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 supplies Olanzapine Impurity 28 (CAS CATO-C4X-117828), a pharmacopoeial impurity reference standard (molecular formula C12H12N4S2, MW 276.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, Olanzapine Impurity 28 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 276.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), Olanzapine Impurity 28 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.
