Chemical Structure

Mianserin Impurity 119 CAS CATO-C4X-1369119 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Mianserin Impurity 119 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 528.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Mianserin Impurity 119 (CAS CATO-C4X-1369119) is a certified pharmaceutical impurity reference standard with the molecular formula C36H40N4 and a molecular weight of 528.73 g/mol.

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.
