Chemical Structure

Mianserin Impurity 120 CAS 77117-73-8 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 120 (CAS 77117-73-8), a pharmacopoeial impurity reference standard (molecular formula C17H18N2O, MW 266.34 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C17H18N2O, Mianserin Impurity 120 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 266.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
