چکیده
In the title compound, C(14)H(11)BrO(2), an ester formed from the reaction of 4-methyl-phenol with 4-bromo-benzoyl-chloride, the dihedral angle between the benzene rings is 54.43 (7)°, indicating a twist in the mol-ecule. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into supra-molecular layers in the bc plane, and these are connected along the a axis by Br⋯Br contacts [3.6328 (5) Å].
