Ethyl 3-benzoyl-2-hydroxy-prop-2-enoate.

In the title compound, C12H12O4, the dihedral angle between the plane through the phenyl ring and the mean plane of the side chain is approximately 14°. The mol­ecules, which contain an intra­molecular O—H⋯O hydrogen bond, are linked end-to-end by weak C—H⋯O inter­molecular hydrogen-bonding contacts, forming infinite one-dimensional chain systems in the crystal structure.
