Abstract: The title compound, C₇H₈N₂O₃, crystallizes with two independent but essentially identical molecules in the asymmetric unit. Each molecule adopts a trans configuration with respect to the C=N bond. The hydrazinecarboxylate group is twisted from the furan ring by 7.78 (13)° in one molecule and by 7.01 (17)° in the other. In the crystal structure, molecules are linked into chains running along [010] by bifurcated N-H(N,O) and N-HO hydrogen bonds. In addition, weak C-HO interactions and an OC short contact [2.896 (3) Å] are observed.
