Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 308.25 g/mol gives Mianserin Impurity 115 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Mianserin Impurity 115 (CAS 764598-05-2) is a certified pharmaceutical impurity reference standard with the molecular formula C17H19Cl2N and a molecular weight of 308.25 g/mol.
Structurally, Mianserin Impurity 115 (C17H19Cl2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 308.25 g/mol, it falls into the moderately-high-molecular-weight range. 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), Mianserin Impurity 115 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.
