1-Butyl-4-hydroxy-3-methylquinoline-2(1H)-one

Abstract

In the crystal of the title compound, C14H17NO2, mol­ecules are arranged into chains along the b axis linked via O—H⋯O hydrogen bonds. While the benzene ring is essentially planar, with a maximum deviation from the best plane of 0.003 (1) Å, the pyridine ring is slightly V-shaped: the distance of the carbonyl C atom from the benzene best plane is 0.120 (1) Å. The hy­droxy group is inclined markedly towards the benzene ring reducing the C—C—O bond angle to 113.21 (10)°.
