Methyl (E)-3-(2-formyl­phen­oxy)acrylate

In the title compound, C₁₁H₁₀O₄, the methyl acrylate sub­stituent adopts an extended E conformation with all torsion angles close to 180°. The conformation of the keto group with respect to the olefinic double bond is typically S-trans. In the crystal, mol­ecules are linked via pairs of C—H...O hydrogen bonds, forming inversion dimers with an R₂²(8) graph-set motif. The dimers are further linked via C—H...O hydrogen bonds, forming chains along [001], which enclose R₃²(16) graph-set ring motifs. The keto group O atomaccepts two C—H...O interactions.
