title: 4-Bromo-5-[(5,5-dimethyl-4,5-dihydro-isoxazol-3-yl)sulfonyl-meth-yl]-3-methyl-1-(2,2,2-trifluoro-ethyl)-1H-pyrazole.
abstract: In the title compound, C(12)H(15)BrF(3)N(3)O(3)S, which has potential herbicidal activity, the mol-ecule is twisted, as indicated by the C-S-C-C torsion angle of 67.86 (19)° for the atoms linking the ring systems. An intra-molecular C-H⋯F short contact occurs and inter-molecular C-H⋯O inter-actions link the mol-ecules in the crystal.
