Haloperidol Impurity 16 CAS 40807-61-2 chemical structure

Description

Haloperidol Impurity 16 (CAS 40807-61-2) is a certified pharmaceutical impurity reference standard with the molecular formula C11H15NO and a molecular weight of 177.24 g/mol.

The molecular framework of Haloperidol Impurity 16 (C11H15NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 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), Haloperidol Impurity 16 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.
