✦ Synopsis

The title compound, C 8 H 10 N 2 O 3 , 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-HÁ Á ÁN, N-HÁ Á ÁO and O-HÁ Á ÁO hydrogen bonds link the molecules.
