Key indicators: single-crystal X-ray study; T = 295 K; mean (C-C) = 0.003 Å; R factor = 0.054; wR factor = 0.181; data-to-parameter ratio = 19.2.In the title molecule, C 10 H 12 O 3 , all non-H atoms lie in a common plane (r.m.s deviation = 0.010 Å ). The molecular conformation is stabilized by an intramolecular O-HÁ Á ÁO hydrogen bond.
