title: 2-[(4-Chloro-benz-yl)carbonyl-meth-yl]benzoic acid.
abstract: The title compound, C(16)H(13)ClO(3), is an important inter-mediate in the conversion of isocoumarin to 3,4-dihydro-isocoumarin. The two aromatic rings are oriented at a dihedral angle of 67.18 (3)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. There is also a C-H⋯π contact between the benzoic acid and 4-chloro-benzyl rings.
