Chemical Structure

Mianserin Impurity 82 CAS CATO-C4X-136982 chemical structure

Description

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.

CATO supplies Mianserin Impurity 82 (CAS CATO-C4X-136982), a pharmacopoeial impurity reference standard (molecular formula C17H20N2O, MW 268.35 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C17H20N2O, Mianserin Impurity 82 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
