Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 229.23 g/mol gives Olanzapine Impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Olanzapine Impurity 29 (CAS 59591-86-5, C12H11N3O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Olanzapine Impurity 29 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Olanzapine 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.
