5-Methyl-2-phenyl-2H-pyrazol-3-ol
The title compound, C(10)H(10)N(2)O, known as Edaravone (MCI-186), was crystallized from methanol. The two independent mol-ecules in the asymmetric unit are linked through an O-H⋯O hydrogen bond. One mol-ecule adopts a ketone form, while the other adopts an enol form. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the b...

The title compound, C(10)H(10)N(2)O, crystallizes with two independent mol-ecules in the asymmetric unit, having closely comparable geometries. The dihedral angles between the 1H-pyrazole and benzene rings in the two mol-ecules are 39.57 (14) and 41.95 (13)°. The two mol-ecules are each connected to neighbouring mol-ecules by pairs of inter-molecular O-H⋯N hydrogen bonds, forming dimers with R(...

The asymmetric unit of the title compound, C(10)H(10)N(2)O, contains two crystallographically independent mol-ecules with similar geometries, which exist in the keto form. The C=O bond lengths are 1.2878 (12) Å in mol-ecule A and 1.2890 (12) Å in mol-ecule B, indicating that the compound undergoes enol-to-keto tautomerism during the crystallization process. In mol-ecule A, the pyrazole ring is ...

The title compound, C(20)H(17)N(3)OS, is a 1H-pyrazol-3(2H)-one having aromatic 4-(1,3-benzothia-zol-2-yl)- and 2-phenyl substituents. The five-membered ring and fused ring system are planar, the r.m.s. deviations being 0.021 and 0.005 Å, respectively. The five-membered ring is aligned at 7.9 (2)° with respect to the fused-ring system. The allyl and phenyl parts of the mol-ecule are both disord...
