Chemical Structure
Description
The molecular framework of 苯并氮杂卓并环衍生物类中间体亚硝胺杂质4 (C12H14ClN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. 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).
苯并氮杂卓并环衍生物类中间体亚硝胺杂质4 (CAS CATO-C3D-262676) is a certified pharmaceutical impurity reference standard with the molecular formula C12H14ClN3O and a molecular weight of 251.71 g/mol.
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), 苯并氮杂卓并环衍生物类中间体亚硝胺杂质4 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.
