Chemical Structure

7-Methyl-5-phenyl-1,3,4,5-tetrahydro-2H-benzo[e][1,4]diazepin-2-one CAS 17972-75-7 chemical structure

Description

Based on its molecular formula C16H16N2O, 7-Methyl-5-phenyl-1,3,4,5-tetrahydro-2H-benzo[e][1,4]diazepin-2-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.31 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.
