Chemical Structure
Description
Based on its molecular formula C24H25N3, (E)-9-ethyl-3-((2-ethyl-2-(o-tolyl)hydrazono)methyl)-9H-carbazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 355.48 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.
