title: 5-Hy-droxy-3-phenyl-5-trifluoro-meth-yl-4,5-dihydro-1H-pyrazole.
abstract: The five-membered dihydro-pyrazole ring in the title compound, C(10)H(9)F(3)N(2)O, is approximately planar (r.m.s. deviation 0.111 Å for all non-H atoms) and its phenyl substituent is aligned at an angle of 14.7 (2)°. Adjacent mol-ecules are linked by N-H⋯O and O-H⋯N hydrogen bonds, generating ribbons running along the b axis of the monoclinic unit cell.
