Mirtazapine Impurity 23 CAS 61337-88-0 chemical structure

Description

CATO supplies Mirtazapine Impurity 23 (CAS 61337-88-0), a pharmacopoeial impurity reference standard (molecular formula C17H18N4, MW 278.35 g/mol) used for the identification and quantification of trace impurities in APIs.

Mirtazapine Impurity 23 (C17H18N4) 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 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
