The title compound, C17H16Br2O3, which is a restricted commercial acaricide (common name bromopropylate), has two independent and conformationally similar molecules in the [dihedral angles between the planes of the two phenyl rings = 68.7 (4) and 77.4 (5)°]. The C atoms of the isopropyl group of one of the molecules are disordered over two sites with occupancies of 0.638 (16) and 0.362 (16). Minor non-merohedral was also present in the crystal. Intermolecular O—H⋯O hydrogen-bonding interactions involving the hydroxy groups and carboxyl O-atom acceptors give separate centrosymmetric homodimers through cyclic hydrogen-bonding motifs [graph set R22(10)].

The title compound bromopropylate was obtained as an analytical reference standard from the U.S. Environmental Protection Agency. Colourless crystal plates suitable for X-ray analysis were obtained by room temperature evaporation of a solution in ethanol.
Hydroxyl H-atoms were located in a difference-Fourier synthesis but were subsequently allowed to ride in the
with Uiso(H) = 1.2Ueq(O). Other H-atoms were included in the at calculated positions [C—H = 0.93 Å (aromatic), 0.97 Å (methine) and 0.96 Å (methyl), with Uiso(H) = 1.2Ueq(aromatic or methine C) or 1.5Ueq(methyl C)], also using a riding-model approximation. Disorder was present in the C-atoms of the isopropyl group of one of the molecules and the occupancies were determined as 0.638 (16) [atoms C31A, C41A, C51A], and 0.362 (16) [atoms C31E, C41E, C51E]. Minor non-merohedral was identified and handled in the (BASF = 0.0779). The maximum difference electron density peak was 1.195 Å-3 (0.90 Å from Br4B).Data collection: CrysAlis PRO (Agilent, 2012); cell

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound C17H16Br2O3, (common name bromopropylate) is the isopropyl ester of 4,4'-dibromobenzilic acid and is available for limited commercial use as a contact acaricide (Acarol, Neorol) (O'Neil, 2001). The structure of benzilic acid (Qui et al., 2007) and its 1-methylpiperidin-4-yl ester (Fu et al., 2006) have previously been reported.
In the structure of the title compound there are two independent and conformationally similar molecules in the asymmetric unit (Figs. 1, 2). The dihedral angles between the planes of the two phenyl rings in these molecules are 68.7 (4) and 77.4 (5)°. However, in one of the molecules the isopropyl group is disordered over two separate sites [C31A, C41A, C51A [S.O.F = 0.638 (16)] and C31E, C41E, C51E [S.O.F. = 0.362 (16)]. Minor non-merohedral twinning was also present in the crystal. Intermolecular hydrogen-bonding interactions involving the hydroxy groups and carboxyl O-atom acceptors (Table 1) give separate centrosymmetric homodimers through cyclic motifs [graph set R22(10) (Etter et al., 1990)] (Fig. 3). Other intramolecular aromatic C—H···O interactions are also present in the dimers as well as relatively short intermolecular Br···O interactions [Br4B···O11Aiii, 3.348 (4) Å; Br4C···O11Ciii, 3.389 (4) Å [for symmetry code (iii), x-1, y, z].
