The molecular structure of the title compound, 2[1-(2,4-dinitrophenyl)-4-methyl-1H-pyrazol-3-yl]phenol, C16H12N4O5, containing a dinitrophenyl and a hydroxy phenyl ring substituted to the pyrazole moiety is one of the products obtained from the reaction of o-hydroxy propiophenone 2,4-dinitrophenylhydrazone. The phenyl and pyrazole rings are quite planar. The dihedral angles between the pyrazole and the two phenyl rings are 23.5(1) and 15.3(1)degrees. The interplanar angle between the phenyl ring is 32.6(1)degrees. The crystal structure is stabilized by O-H ... N-, and O-H ... O-type intramolecular hydrogen bonds and the packing of the molecules are stacked by C-H ... O-type intermolecular hydrogen bonds.
