Description

Vilazodone Impurity E, 5-(4-(4-(5-cyano-1-(4-(5-cyano-1H-indol-2-yl)butyl)-1H-indol-3-yl)butyl)piperazin-1-yl)benzofuran-2-carboxamide, is a structurally elaborated process-related impurity of the vilazodone scaffold, containing dual cyanoindole motifs, a piperazine linker, and a benzofuran carboxamide core. With molecular formula C39H39N7O2 and molecular weight 637.77 g/mol, it may arise from late-stage coupling, alkylation overreaction, or regioselective side pathways during construction of the bis-indole side chain. Because of its size and aromatic density, confirmation typically relies on LC-MS/MS, high-resolution MS, and orthogonal HPLC-UV or LC-CAD profiling; no nitrosamine functionality is present, but impurity control remains relevant under ICH Q3A and ICH M7 principles.
