Chemical Structure

Mianserin impurity 20 CAS CATO-C4X-136920 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 313.84 g/mol gives Mianserin impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Mianserin impurity 20 (CAS CATO-C4X-136920), a pharmacopoeial impurity reference standard (molecular formula C19H22ClN2, MW 313.84 g/mol) used for the identification and quantification of trace impurities in APIs.

Mianserin impurity 20 (C19H22ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Mianserin impurity 20 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.
