Abstract: The title compound, C₁₄H₁₄O₃, was obtained by the Williamson method using 2,2'-dihydroxy-1,1'-biphenyl with chlorohydrin. The asymmetric unit contains two crystallographically independent molecules which differ slightly in the orientations of the hydroxyethoxy side chains. In each independent molecule, an intramolecular O-HO hydrogen bond is observed. In the solid state, each of the two independent molecules forms an O-HO hydrogen-bonded centrosymmetric dimer. The crystal packing is further stabilized by C-H interactions.
