3‐Hydroxy‐4‐methoxybenzohydrazide

The title compound, C8H10N2O3, is an important inter­mediate for the synthesis of biologically active heterocyclic compounds. The planar hydrazide group is oriented at a dihedral angle of 25.15 (3)° with respect to the benzene ring. In the crystal structure, inter­molecular N—H⋯N, N—H⋯O and O—H⋯O hydrogen bonds link the mol­ecules.
