The title compound, C18H13BrN2O2, was synthesized by the reaction of 2-hydroxy-1-naphthaldehyde with an equimolar quantity of 3-bromobenzohydrazide in methanol. The dihedral angle between the benzene ring and the naphthyl ring system is 18.3 (2)°. An intramolecular O-HN hydrogen bond is observed between the phenolate O and imine N atoms. In the crystal structure, molecules are linked through intermolecular N-HO and C-HO hydrogen bonds, forming a chain running along .
