5-(2-Hydroxyphenyl)-3-methyl-4,5-dihydro-1H-pyrazole-1-carbaldehyde

Abstract

In the title compound, C11H12N2O2, the dihydropyrazole and benzene rings are oriented at a dihedral angle of 68.35 (5)°. The dihydropyrazole ring is planar, with a mean deviation from the mean plane of 0.0409 Å. The crystal structure is stabilized by O—H...O and C—H...O hydrogen bonds.
