In the title molecule, C10H12O3, 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—H⋯O hydrogen bond.

To a methanolic solution of 2-hydroxy-5-methyl-1,3-benzenedicarboxaldehyde (1g, 6mmol) decarborane (0.37, 3 mmol) was added slowly with constant stirring at room temperature in nitrogen atmosphere for 24 hours. A pale yellow solution formed after 24h and was concentrated to get the crude product. The crude product was washed well with methanol and dried in vacuum. The product was recrystallized in chloroform to get pale yellow coloured crystals suitable for single crystal XRD. yield 0.96g, 80% .
H atoms were positioned geometrically and refined using riding model with C-H = 0.93Å and Uiso(H) = 1.2Ueq(C) for aromatic C-H, C-H = 0.97Å and Uiso(H) = 1.2Ueq(C) for CH2, C-H = 0.96Å and Uiso(H) = 1.5Ueq(C) for CH3 and O-H = 0.82Å and Uiso(H) = 1.2Ueq(C) for OH.

In recent days methylbenzene (toluene) and substituted methylbenzene have become very important on account of their wide range of applications in medicine and industry (Anbarasan et al., 2011). For example 3-chloro-2-methylbenzene-1-sulfonylchloride shows the biological activity of hydroxysteriod dehydrogenase inhibitors (Chan & Daniels, 2007).
The geometric parameters of the compound (I), (Fig. 1) agree well with those of a reported similar structure (Wang et al., 2011; Kılıç et al., 2009) The molecular structure is stabilized by an intramolecular O-H..O interaction generating a six-membered ring S(6) graph-set motif (Bernstein et al., 1995).
