The title compound, C10H12O3, crystallizes in the ortho­rhom­bic P212121 space group. The structure contains a phenolic group with the OH being coplanar with the phenyl ring. The structure exhibits significant hydrogen bonding between the O—H group of one mol­ecule and the CO group of an adjacent one. These O—H⋯O=C inter­actions form chains of mol­ecules parallel to the b axis. No ππ or C—H⋯π inter­molecular inter­actions are observed.

Structure description

The application of nitro­gen-based fertilizers has been a remarkable strategy applied to meet the growing world food and fibre demands over the past 80 years (Galloway et al., 2008[Galloway, J. N., Townsend, A. R., Erisman, J. W., Bekunda, M., Cai, Z., Freney, J. R., Martinelli, L. A., Seitzinger, S. P. & Sutton, M. A. (2008). Science, 320, 889-892.]). However, these fertilizers increase anthropogenic nitrous oxide production, causing serious effects on the environment in water, the air and soil. One of the important environmentally friendly techniques applied in agriculture to control the rate of the climate-relevant N2O gas emission is the use of nitrification inhibitors (Ruser & Schulz, 2015[Ruser, R. & Schulz, R. (2015). J. Plant Nutr. Soil Sci. 178, 171-188.]). Among the various nitrification inhibitors, methyl 3-(2 or 4-hy­droxy­phen­yl)propionates (MHPPs) are the most important formed in sorghum (Sorghum bicolor; Zakir et al., 2008[Zakir, H. A., Subbarao, G. V., Pearse, S. J., Gopalakrishnan, S., Ito, O., Ishikawa, T., Kawano, N., Nakahara, K., Yoshihashi, T., Ono, H. & Yoshida, M. (2008). New Phytol. 180, 442-451.]; Nardi et al., 2013[Nardi, P., Akutsu, M., Pariasca-Tanaka, J. & Wissuwa, M. (2013). Plant Soil, 367, 627-637.]). Additionally, they exhibit an inter­esting motif in the enzymatic coupling of saccharides to proteins, also acting as modulators of the root system architecture (RSA; Martinez et al., 2017[Martinez, A. P., Qamar, B., Fuerst, T. R., Muro, S. & Andrianov, A. K. (2017). Biomacromolecules, 18, 2000-2011.]; ter Haar et al., 2011[Haar, R. ter, Wildschut, J., Sugih, A. K., Möller, W. B., de Waard, P., Boeriu, C. G., Heeres, H. J., Schols, H. A. & Gruppen, H. (2011). Carbohydr. Res. 346, 1005-1012.]). There are various reports on the synthesis of methyl 3-(2-hy­droxy­phen­yl)propionate (Yuthavong et al., 2012[Yuthavong, Y., Tarnchompoo, B., Vilaivan, T., Chitnumsub, P., Kamchonwongpaisan, S., Charman, S. A., McLennan, D. N., White, K. L., Vivas, L., Bongard, E., Thongphanchang, C., Taweechai, S., Vanichtanankul, J., Rattanajak, R., Arwon, U., Fantauzzi, P., Yuvaniyama, J., Charman, W.

(2013). Coloration Technol. 129, 418-424.]), we report herein the crystal structure of methyl 3-(2-hy­droxy­phen­yl)propionate.

The mol­ecular structure of the title compound is depicted in Fig. 1[link]. The phenyl ring is planar with the hydroxyl group being coplanar with a C2—C1—O1—H1H torsion angle of −8 (2)°. The bond distances and angles within the phenolic ring, the propionate group and the co-planarity of OH group with the phenyl ring are consistent with related structures such as methyl 3-(3,5-di-tertbutyl-4-hy­droxy­phen­yl)propionate (Li et al., 2014[Li, X., Wang, Z.-G., Chen, H.-H. & Liu, S.-G. (2014). Acta Cryst. C70, 1050-1053.]), 2-(4-acetyl­anilino)-2-oxoethyl 3-(4-hy­droxy­phen­yl)propionate (Ashraf et al., 2016[Ashraf, Z., Kim, D., Seo, S.-Y. & Kang, S. K. (2016). Acta Cryst. E72, 933-936.]) and methyl 3-[3-tert-butyl-5-(6-chloro-1-oxybenzotriazol-2-yl)-4-hy­droxy­phen­yl]pro­pion­ate (Wen et al., 2006[Wen, H.-L., Chen, Y.-H., Hu, H.-W., Zhou, X.-Y. & Liu, C.-B. (2006). Acta Cryst. E62, o4702-o4703.]).

The crystal structure exhibits significant hydrogen-bonding inter­actions (Table 1[link]), in which the O1—H1 groups acts as the donor while the carbonyl group of an adjacent mol­ecule (–x + 1, y + [{1\over 2}], –z + [{3\over 2}]) being the acceptor. These hydrogen bonds shown as dashed lines in Fig. 2[link]) connect the mol­ecules into chains running parallel to the b axis (Fig. 3[link]). ππ stacking and C—H⋯π inter­actions are not present in the crystal structure.

Synthesis and crystallization

A mixture of di­hydro­coumarin (1 ml, 7.89 mmol), a catalytic amount of conc. H2SO4, and 30 ml of dry MeOH were heated under reflux for 5 h. The methanol was removed in vacuo and the residue was neutralized with saturated NaHCO3 solution then diluted with water and extracted with Et2O. The combined organic extracts were dried over MgSO4, filtered and concentrated. The crude compound was crystallized by slow evaporation of a diethyl ether–hexane mixture (2:1 v/v) to give colourless single crystals (1.22 g, 86%). M.p. 41–42°C; IR (KBr, cm−1) 3420, 3055, 1735, 1447. 1H NMR (400 MHz, CDCl3) δ 2.76 (t, J = 6.6 Hz, 3H), 2.95 (t, J = 6.6 Hz, 2H), 3.72 (s, 3H), 6.89 (d, J = 7.4 Hz, 2H), 7.12–7.16 (m, 2H). 13C NMR (100 MHz, DMSO-d6) δ 24.86, 34.87, 52.24, 116.82, 120.81, 127.07, 128.23, 130.52, 154.26, 175.96.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. All hydrogen atoms on carbon atoms were calculated with C–H = 0.95, 0.98 and 0.99 Å for CH (aromatic), CH2 and CH3, respectively, and refined as riding atoms with Uiso(H) = 1.2 Ueq(C) for CH (aromatic) and CH2, and 1.5 Ueq(C) for CH3. The H atoms of the –OH group was located in a differenceFourier map and refined without any constraint.
