(E)-4-Amino-N′-(2-hy­dr­oxy-5-methyl­benzyl­­idene)benzohydrazide.

The asymmetric unit of the title compound, C15H15N3O2, comprises two crystallographically independent mol­ecules (A and B), each having an E conformation around the C=N bond. In each mol­ecule, there is an intra­molecular O—H⋯N hydrogen bond making an S(6) ring motif. The dihedral angles between the substituted phenyl rings are 17.49 (9) and 10.03 (9)°. In the crystal, N—H⋯O hydrogen bonds link neighbouring independent mol­ecules into infinite chains, of the type –A–B–A–B–, along the a axis, enclosing R21(7) ring motifs. The chains are linked by N—H⋯O hydrogen bonds and C—H⋯O inter­actions, leading to the formation of a three-dimensional network
