4-(benzeneazo) salicyladelhyde was synthesized with aniline and salicylaldehyde. Benzoylhydrazine and p-hydroxybenzoylhydrazine were synthesized using the reaction of ethyl benzoate and methyl p-hydraxy benzoate with hydrazine hydrate. Four novel 4-(benzeneazo) salicyladelhyde hydrazones were synthesized using the reaction of 4-(benzeneazo) salicyladelhyde with benzoylhydrazine, p-hydroxybenzoylhydrazine, phenylhydrazine, and isonicotinyl hydrazine respectively. IR, UV and the fluorescence spectrum of 4-(benzeneazo) salicyladelhyde hydrazones were studied.
