Chemical Structure

Mianserin Impurity 78 CAS CATO-C4X-136978 chemical structure

Description

The occurrence of Mianserin Impurity 78 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Mianserin Impurity 78 (CAS CATO-C4X-136978) is a certified pharmaceutical impurity reference standard with the molecular formula C17H16N2 and a molecular weight of 248.32 g/mol.

Mianserin Impurity 78 (C17H16N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Mianserin Impurity 78 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.
