6-Hydroxy-5,7,8-trimethylchroman-2-one

Abstract

The title compound, C12H14O3, consists of a chromanone unit with an –OH substituent at the 4-position and methyl substituents on the remaining C atoms of the aromatic ring. The fused pyranone ring adopts a distorted envelope conformation with the methylene group adjacent to the carbonyl carbon as the flap atom. The crystal structure is stabilized by classical O—H...O hydrogen bonds and weak C—H...O and C—H...π interactions, generating a three-dimensional network.
