2-Hydroxy-4,6-dimethoxy-3-(3-methylbutanoyl)benzaldehyde.
The structure of the title compound, C(14)H(18)O(5), has two independent molecules related by a local noncrystallographic a-glide plane perpendicular to the b axis. The pseudo-glide plane shows a discontinuity at z = 0. Both molecules have an intramolecular hydrogen bond between the hydroxy and aldehyde groups. There are stacks of molecules along the a-axis direction. Neighboring molecules in the stack have an interplanar angle of 1.6 (1) degrees , interplanar distances ranging between 3.399 (3) and 3.417 (3) A, and a ring offset of 1.38 (1) A.
