title: 5-Hy-droxy-3-methyl-5-phenyl-4,5-di-hydro-1H-pyrazole-1-carbothio-amide.
abstract: In the title compound C(11)H(13)N(3)OS, the aromatic ring and the dihydro-pyrazole ring are oriented orthogonally with respect to each other, making a dihedral angle of 89.92 (9)°. An intra-molecular O-H⋯S hydrogen bond occurs. In the crystal, weak N-H⋯N and N-H⋯S hydrogen bonds link the mol-ecules into a columnar stack propagating along the b axis.
