Abstract: In the title compound, C₁₀H₂₀N₄O₃, the piperazine ring adopts a chair conformation. The molecule adopts an E conformation across the C=N double bond, with the -OH group and the piperazine ring trans to one another. Further, the H atom of the hydroxy group is directed away from the NH₂ group. An intramolecular N-HO contact occurs involving the NH₂ group and the oxime O atom. In the crystal, molecules are linked via strong N-HO and O-HN hydrogen bonds with alternating R₂²(6) and C(9) motifs into tetrameric units forming R₄⁴(28) motifs.
