Synthesis and characterization of (E)-2-(1-hydrazonoethyl)-4,5-dimethylphenol from 2-hydroxy-4,5-dimethylacetophenone


This study reports the development of a novel substituted hydrazone prepared from 2-hydroxy-4,5-dimethylacetophenone and hydrazine in alkaline medium at controlled conditions which yields as corresponding hydrazone [(E)-2-(1-hydrazonoethyl)-4,5-dimethylphenol]. The structure of synthesized (E)-2-(1-hydrazonoethyl)-4,5-dimethylphenol was elucidated by elemental analysis and spectroscopic techniques like infrared spectroscopy, ultraviolet–visible spectroscopy, high-performance liquid chromatography, proton nuclear magnetic resonance and mass spectrum.
