Chemical Structure
Description
As a certified reference material (CRM), Mirtazapine Impurity 5 HCl 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.
Mirtazapine Impurity 5 HCl (CAS 6407-19-8) is a certified pharmaceutical impurity reference standard with the molecular formula C11H15Cl2NHCl and a molecular weight of 268.61 g/mol.
Structurally, Mirtazapine Impurity 5 HCl (C11H15Cl2NHCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 268.61 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
