Chemical Structure

Olanzapine Impurity 11 CAS 1017241-36-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 328.43 g/mol gives Olanzapine Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Olanzapine Impurity 11 (CAS 1017241-36-9) is a certified pharmaceutical impurity reference standard with the molecular formula C17H20N4OS and a molecular weight of 328.43 g/mol.

Olanzapine Impurity 11 (C17H20N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 11 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.
