Abstract: The crystal structure of the title compound, C₇H₉BrN₂O₂, has been determined in the triclinic space group P. There are three molecules in the asymmetric unit, arranged with approximate threefold rotation symmetry, and the three pyrazole rings are almost coplanar. A bromine atom at the 4-position of the pyrazole ring provides the possibility for synthesis of substituted pyrazole derivatives. Packing is governed only by van der Waals interactions.
