Agomelatine Impurity 33 CAS 1079774-32-5

Description

The occurrence of Agomelatine Impurity 33 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Agomelatine Impurity 33 (CAS 1079774-32-5) is a certified pharmaceutical impurity reference standard with the molecular formula C12H9NO and a molecular weight of 183.21 g/mol.

Agomelatine Impurity 33 (C12H9NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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), Agomelatine Impurity 33 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.
