Description
As a certified reference material (CRM), Trazodone Impurity 87 HBr 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.
Trazodone Impurity 87 HBr (CAS CATO-C4X-177287) is a certified pharmaceutical impurity reference standard with the molecular formula C13H18BrClN2HBr and a molecular weight of 398.57 g/mol.
The molecular framework of Trazodone Impurity 87 HBr (C13H18BrClN2HBr) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. 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. 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.
